In the year 60 AD, the Roman Empire has taken over most of Europe except for Britannia,
which still resists. On the island of Mona, the Roman army arrives to kill three hundred druids,
slaying them one by one without mercy. But even in their last moments, the druids never stop
believing that one day their mythical warrior goddess will save their people from the Romans,
so they die praying on their knees. Later in Rome, Commander Paulinus reports the latest massacre to
King Nero, commenting on the druid’s legend of a warrior goddess. Nero agrees they can’t allow the
druids to find a savior, so he issues a decree that forbids all women from holding a position
of power. Meanwhile in Brittania, the Iceni tribe is living in peace under the leadership of
King Prasutagus and his Queen, who are the proud parents of two young girls. One morning, warrior
Ciaran informs Prasutagus that Rome has sent a new procurator called Catus, who doesn’t like
Britannia much. While the men discuss politics, the queen takes the girls to language classes
and a cosmetic session. Once they’re all nice and pretty, they make their way to the market,
only for the girls to get disturbed when they find a bunch of men killed on crosses. At first the
queen doesn’t see the big deal since she thinks they’re criminals that got their sentence, but her
maid corrects her: those dead men are actually Christians that Rome killed for their beliefs.
The queen refuses to be intimidated and takes the girls to the market anyway. While they look
around, they notice a group of Trinovante warriors having a drink. Suddenly Cartimanda sees the queen
and kneels before her as she calls her Boudica, the name of the warrior goddess. When they hear
that, the other warriors kneel along, but a stall owner hears the maid explain the goddess legend to
the girls and protests in the name of Rome. The man tries to grab the queen to take her to the
Roman guards, but Cartimanda immediately cuts his hand and then decapitates him. Afterward everyone
runs away before the Roman guards can find them. Sometime later, Prasutagus explains he had to
negotiate and bargain with the centurions to prove his wife’s innocence. For around a year, the queen
isn’t allowed to return to the market, anything she wants she must send a servant for. Then the
queen asks him why the Trinovante warriors saw her as their goddess, so Prasutagus guesses it’s
because of her barbarian blood. In the afternoon, the queen plays with the girls using training
swords, but it’s clear none of them have proper training. Prasutagus soon joins them while Ciaran
announces he’s leaving, and the queen notices he’s been in a constant broody mood since he lost his
family in the war. Then she teases her husband with the wooden sword, which makes Prasutagus
think the barbarian blood in her is stronger than he thought. Since obviously the queen can’t leave
her origins behind, Prasutagus decides to gift her the dowry her father gave him when he married her:
it’s the Boudica sword, which was forged by forgotten magic and protected for centuries by
the druids. Its color changes with the flickering fire. The next day, procurator Catus visits the
Iceni tribe and Prasutagus has no choice but to kiss his ring. They have a nice meal together
and the locals pretend to be honored by Catus’ presence, but they’re clearly uncomfortable by his
passive-aggressive comments toward their culture and his admiration of their fort, which implies he
wants to steal it from them. Afterward, Prasutagus orders his men to be well-behaved because Catus
can choose to destroy the village over the smallest mistake. He asks Ciaran to round up
a bunch of bandits and undesirables to send them to Catus as tribute as an indirect way to show him
the lands are dangerous and hopefully kill any ideas of him settling down here. Ciaran obeys
his king, but he doesn’t like the idea. Sometime later, Prasutagus leaves with his men to catch all
those bandits for tribute. After a few days they come back but Ciaran has bad news for the queen:
while they were fighting the bandits, they were ambushed and Prasutagus died in battle. The queen
has a total breakdown and sends the men away, yelling at them for not protecting their king.
The next day, since there are no male heirs, the Iceni tribe declares her their new Queen Leader
and gives her the royal torque that marks her as such. Ciaran doesn’t look too happy with this
decision. The ceremony is suddenly interrupted by Catus and his men, and he explains the Roman
Empire doesn’t accept women in positions of power and that now he considers the tribute they sent
him a bribe. Because of these two crimes, Catus will take all her land and she will be punished
together with her daughters. He also reveals that Ciaran was the one who told him Prasutagus’
location so that his soldiers could ambush him. The soldiers immediately drag the queen away from
her daughters, throw away her torque, and tear off her clothes before hanging her on a tree,
where they proceed to flog her. As the queen is hit over and over, the tribe can only watch,
because those who try to protest are held down by the soldiers. After the punishment is over,
they brand her face with Nero’s initials, an act usually reserved for slaves. In the evening,
Cartimanda and the Trinovante warriors sneak into the Roman camp and silently kill a bunch of
guards until they find where the queen is being held and take her away. By crossing the river,
they manage to move unnoticed and make it to the Trinovante tribe, where they take care of
the queen’s wounds. While she rests, she suffers a fever and keeps asking about her daughters, so
Cartimanda has to tell her the Trinovante tribes are her children now. The queen refuses to accept
it, but thankfully at that moment the girls enter the tent and reunite with their mother. Cartimanda
also gifts her a set of fake teeth that she stole from a centurion because a warrior must be able to
bite. A few days later when she’s finally feeling better, the queen leaves the tent and discovers
the warriors are training her daughters to fight. She asks them to take a break so they can spend
some time together and learns that Cartimanda used to have children too, but they were killed by the
Romans. The girls also explained that in the eyes of the Trinovante tribe, the mark Catus gave her
brands her as their leader and that her duty is to bring the tribes together to fight the Romans.
The girls even tell her that she has no choice. Later, the queen decides to train with a dummy,
but her movements are clumsy. Luckily one of the warriors joins her and guides her on how
to hit correctly. Their training session is interrupted by Cartimanda, who brings her the
Boudica sword. Apparently Catus had given it to one of his soldiers and Cartimanda killed the guy
to recover it. The queen is incredibly touched by the gesture, but her trainer comments that bronze
isn’t a good metal for a sword. At that moment, Wolfgar and his tribe arrive to meet the queen.
Wolfgar isn’t impressed by her lack of experience and proper armor, saying he should be the one
leading. He then proceeds to make fun of her sword and breaks it in two before throwing it into the
river. The queen rushes to jump into the water to recover the sword, which worries the warriors
because those currents are strong enough to drown a person. However the queen comes back and shows
the sword magically fixed itself, which impresses everyone and causes them to kneel as Wolfgar
announces she can depend on him and his men. The queen raises her sword and finally accepts
the name of Boudica. In the evening, the warriors recover the royal torque as well and do a ceremony
that officially welcomes Boudica as the new queen of the united tribes. She offers a heartful speech
about regaining their freedom and mentions they can ambush Cartus’ convoy in two days. Woflgar is
skeptical because Cartus has a powerful army and it’d be like walking to their deaths, but Boudica
makes her sword float back to her hand before leaving and everyone sees it as another sign.
While Boudica is in the forest ready to fight alone, Wolfgar shows up with his men and they
accept to help her fight while chanting her name. Two days later, the convoy is crossing the forest
while being led by Ciaran, who is now part of the Roman army. They find Boudica alone in the middle
of the road and she asks to parlay with Cartus. At first Ciaran tries to ignore her request,
but she threatens with great violence until he goes looking for his boss. Cartus shows up and
doesn’t recognize Boudica, so she takes the chance to remind everyone that she’s the queen of these
lands before calling her sword and killing Cartus with quick movements. At that moment the tribe
warriors come out and surround the Romans in a very successful ambush. Soon there are fights
all over the area as the Romans try to defend themselves or run away, but Boudica’s men are
ruthless and kill every single enemy they put their eyes on. Boudica sometimes loses her foot
or her sword, but she never gives up and keeps going until there isn’t a single Roman left and
their heads are impaled on spikes. When it’s all over, the tribesmen take gold and anything
useful from the bodies. Two warriors find Ciaran trying to get away and bring him to Boudica,
and the mere sight of him makes her so mad that she starts stabbing him over and over for his
treason. A worried Wolfgar has to pull Boudica back before she loses her mind, and she announces
they’ll ride for Camulos. Wolfgar thinks it’s a good idea, but they’ll have to get a blessing
from the druid council first. In the evening, the druids give them their blessing by making
Boudica and Wolfgar drink from Catus’ skull as tradition dictates. After the blessing is done,
Wolfgar tries to flirt with Boudica even though he already has two wives, but she turns him down
because she still considers herself to be the wife of King Prasutagus. After Boudica is left alone,
another druid comes to talk to her about the meaning of life. She tells Boudica that her
daughters actually died and she refuses to accept it. Boudica starts thinking about all the family’s
memories together as the druid explains that her daughters' spirits will always be with her and
that she’ll die soon, but first she must lead her army again. Upset by all these revelations,
Boudica leaves the shack to ask Wolfgar if he can see her daughters and he confirms they’re
just her imagination. This causes her to have a breakdown and pass out. Moments later, Boudica
wakes up in a bed and sees her daughters’ spirits by her side. This time she knows they aren’t real,
but she still appreciates their support and promises they’ll reunite soon. A few days later,
Boudica and her army arrived at Camulos. This town was occupied by the Romans after they
murdered all the locals and made it a retirement settlement for their senior soldiers. It’s easy
for Boudica’s group to invade the town and kill all the Romans because of their old age, causing a
complete massacre with heads decapitated included. The fight is over in just a few moments, and after
they’ve taken anything valuable, they set the whole settlement on fire and Boudica announces
they just got started. Later after they’ve set up camp, Boudica notices the warriors are celebrating
in a very peculiar way. Wolfgar explains they are getting the same mark she has on their cheeks as
a way to pay tribute to her, which upsets Boudica because the symbol equals slavery. However Wolfgar
points out they can’t read, so they’re giving the symbol a new meaning. When they make it
to Cambridge Forest, they ambush another Roman convey and dozens of soldiers are killed with no
mercy. The more they fight, the more coordinated Boudica’s army becomes but also the more vicious,
and heads are decapitated left and right. Later in London, Boudica’s army attacks the harbor
in the middle of the night and burns down their enemy’s ships. The Roman soldiers try their best
to hold the line, but there’s nothing they can do against these furious tribesmen and Boudica takes
great pleasure in decapitating their captain. Meanwhile in Rome, riots are taking over the
city and buildings are burning down. People aren’t happy with how costly war is and are demanding a
victory. Paulinus tries to rescue Nero, but the king explains he’s a musician, not a warrior. He
feels that Roman has forsaken him, so he decides to self-delete. Paulinus is devastated to see his
king die, but he swears to bring the victory that Rome needs and tells his troops they’ll be sailing
in the morning. Soon the news of Nero’s death and Paulinus’ trip reaches Britannia, and the
tribesmen are worried because the king’s army is more powerful than average guards. Wolfgar has a
chat with Boudica, explaining that the tribesmen need to recuperate and that winter is coming.
Fighting now would mean walking to their deaths, so he thinks the best course of action is to
return in the spring with more men from the North. Boudica refuses to send her men home, saying they
need to finish what they started. The spirits of her daughters point out that Wolfgar is probably
mad because she turned him down, but Boudica still doesn’t want to lay with him even if it’s for the
greater good. They can’t reach an agreement so Wolfgar takes his men away, and Boudica is left
with only the Trinovante tribe. The next morning, the tribe gets ready to fight and they learn that
Paulinus is making his way to Watling Street to meet her. Boudica is eager to go, so she gives her
tribe an encouraging speech and kisses the land, promising to get back their freedom. The tribesmen
run toward the road to start their attack, but to their shock, the soldiers move out of the
way to let them pass. Paulinus is an experienced strategist and has prepared the perfect ambush
with dozens of archers that soon open fire and start killing the tribesmen. Horrified,
Boudica orders her men to turn her carriage on its side for protection, but it’s pointless:
many of her men are still fighting and they keep dropping like flies. Boudica tries asking her
daughters for help, but the girls explain her time is finally over and she must join her family. She
decides she doesn’t want to die like a coward and Cartimanda shows her support, so Boudica
gives her orders and everyone comes out to go down fighting. At that moment they hear screaming from
the forest and discover that Wolfgar has come back with his men to help, surprising the Roman
soldiers from behind and using their own crossbow to fight. Romans start falling all over the place,
but their numbers are still greater, so soon both Wolfgar and Cartimanda fall in battle.
Boudica suffers from seeing these deaths and furiously kills as many Romans as she can,
but her daughters remind her it’s time to reunite with her family. While she’s distracted by their
spirits, Boudica is hit by an arrow and the Romans take the chance to surround her, killing her with
multiple stabs. As she dies, Boudica thinks of her family and her soul reunites with them in
the afterlife. At the present time, there’s a statue of Boudica and her daughters in London.
