In a dark room, four mercenaries drop dead to the floor, causing Andy to think about all the times
she died and wonder if this is her last time. It all begins a day before in Morocco, when Andy
meets with Booker to chat about a possible new job for them. Andy hesitates because she doesn't want
to fight anymore, but Booker convinces her to at least come back to the hotel and see the others.
On their way there, Andy notices some girls taking a picture that accidentally includes her, so she
makes up an excuse to borrow the phone and deletes every evidence of their presence. At the hotel,
they reunite with couple Nicky and Joe after a long time. All the guys want to take the job but
Andy is still hesitant because she doesn’t trust Copley and they have a rule to never work with the
same employer twice. In the end, they convince her to go with Booker to have a meeting with
Copley just to see what he has to say. Sometime later, Andy and Booker sit outside at a cafe while
Nicky and Joe watch from the hotel window just in case. Copley arrives and explains everything:
he decided to take a break from the CIA when his wife got sick, but when she died,
he couldn’t bring himself to go back. Nowadays he pays himself for these kinds of jobs and
wants their team to do this one. The mission would be saving some hostages in South Sudan
and when Copley says how they could help make a big difference, Andy finally accepts. Afterward,
the team flies to South Sudan and waits for night to fall to strike. They silently
kill all the guards outside one by one and then sneak through the fence to kill a few
more. The building’s door is destroyed with a small explosive, but when they make it inside,
they’re shocked to discover that there actually are no hostages. Andy realizes they’ve been set
up right before a bunch of soldiers enter the room and open fire, causing the team to fall to the
ground with blood spreading around them. Thinking the team is dead, the soldiers turn their backs,
but soon the team’s bodies start to heal rapidly and even expel all the bullets. The four of them
soon get up from the ground and kill all the soldiers with a variety of fighting techniques,
not caring if they get hurt in the process. All this is seen by Copley through security cameras,
which Andy notices and destroys. The next morning, the team buries their bloody clothes in the sand
and discusses their options. Andy says that they have to find Copley and kill him because they
know their secret: they’re centuries-old warriors with regenerative healing abilities who work to
help people as mercenaries. But after they find Copley, she’s decided she'll be done fighting
for the world. Meanwhile in Afghanistan, soldier Nile of the American forces is on
a mission to check on a group of women that might be held hostage by an enemy. When she finds them,
they silently send her in the direction of the man, and Nile enters the building with her team,
quickly shooting the guy in the chest. Then Nile moves to check on the body, but the man slices her
throat. A teammate rushes to cover Nile’s wound but she still dies. At that moment, the team is
sleeping on a train and they begin having dreams of Nile being killed while in the medic tent,
Nile is alive and dreaming of the team in return. The team wakes up and realizes that these dreams
mean that there’s another one of them, which frustrates Andy because she wants to get this
done quickly. The guys have to convince her this is a sign and they need to find Nile, so Andy
says she’ll go do it herself while they work on tracking down Copley. They agree to meet in France
later. Back to Nile, she realizes her friends are all wary of her now because she doesn’t even have
a scar from the injury. The incident is reported and the higher-ups decide to send Nile to Germany
for some testing. An upset Nile returns to her tent and her mood gets worse when she discovers
that her friends have already packed her things. In England, pharmaceutical executive Merrick gives
a presentation about stem cell research, telling a wealthy public that he has the technology to
end human disease and prolong our lifespan, all he needs is investment. Afterward, Merrick meets with
Copley, who shows him the footage of Andy’s team coming back to life. However Merrick is unhappy,
explaining that he needs hard evidence because people will just think the video was edited. He
needs Copley to capture them and bring them to him. While Nile waits for a helicopter to pick
her up, Andy cuts in and knocks all the guards out before doing the same to Nile. Moments later Nile
wakes up in the trunk of an army vehicle driven by Andy and immediately tries to escape by kicking
out the back. Nile falls to the ground and Andy quickly stops driving to go after her, so Nile
tries to run away but Andy stops her by shooting the back of her head. Then Andy waits for Nile
to come back to life and Nile responds by stabbing her on the shoulder. Andy isn’t bothered and tells
her that if she wants answers, she’ll have to come with her. Afterward, Andy and Nile take a
plane to France that is currently participating in a trafficking operation. Andy calls the team
to inform them she’s got the girl, but they don’t have info on Copley yet. Before they leave, Andy
destroys her phone. Then she tells Nile about her team and the fact they have no idea why they’re
immortal, but Nile doesn’t find these vague answers very satisfying. After Andy falls asleep,
Nile binds her to her chair and holds a gun to the pilot's head to make him fly back. When Andy wakes
up, she talks to the pilot in Russian, telling him to play dead so she can distract Nile. Andy
pretends to shoot the pilot and the plane starts falling, so when Andy says she knows how to pilot,
Nile releases her. Then the pilot regains control of the plane and corrects their course back to
France while Nile and Andy get in a fight. With way more years of experience, Andy easily wins and
gives Nile some serious wounds to calm her down. As the girl watches her injuries heal on their
own, Andy finally convinces her to collaborate. Later in France, they meet with the rest of the
team in an old abandoned church, where they have dinner and Nile gets to learn more about the team.
Booker became immortal in the 18th century, Nicky and Joe were enemies at the Crusades, and Andy
says that she is the oldest but doesn’t remember her actual age. The team also tells Nile that it
is possible for them to die, but it is very rare. After an immortal has been alive for long enough,
their wounds just stop healing, indicating it’s their time. Afterward they all go to sleep except
for Andy, who stays on a chair in the living room. In the middle of the night, Nile has a nightmare
that wakes everyone up. She explains that she saw a woman in a coffin drowning in the sea and the
team tells her that was Quynh, another immortal that used to fight alongside Andy. Back then they
had been attempting to free women accused of witchcraft, but they were caught and accused
of witchcraft themselves. Soon the town realized they couldn’t die so they made a special plan:
they separated the women and locked Quynh in an iron coffin, which was thrown into the ocean.
Since then, Quynh has been drowning over and over, reviving and dying again forever. Upset by
this story, Nile rushes outside and Andy follows her to tell her they’re all she’s got. Suddenly,
they hear Copley’s soldiers arrive. As Copley watches everything from a surveillance van,
the women go back inside and discover that Joe and Nicky are nowhere to be found and Booker has
been blown up by a grenade, which takes a while to heal. Then Nile waits with Booker while Andy
goes after the soldiers. Once again, she jumps into the fight without caring about getting hurt
and defeats everyone in seconds, which causes Copley to go away in fear. Once it’s over,
the group packs their things and goes looking for another hideout. Meanwhile Joe and Nicky wake up
in a van surrounded by soldiers, who make fun of them for being a couple and keep them apart when
they try to kiss. Soon the van takes them to an airport, but when the doors are opened it’s
revealed that Joe and Nicky have killed everyone while still being handcuffed. Copley puts them on
a plane to England and takes them to see Merrick, who stabs them for fun as he explains that he’ll
put them through experiments until he figures out how to make the human lifespan longer. Next
Nicky and Joe are sedated and sent to a lab while Merrick demands that Copley bring him the others
too. Back to Andy, she, Booker, and Nile take shelter in an abandoned mine, where Nile is
shocked to find all the old treasure and original art they hid there. While Booker tells Nile about
his dead kids and the pain of living forever while their loved ones die, Andy realizes that
her wounds aren’t healing. She leaves the mine to drive to a pharmacy in town, where she buys
medical supplies and is surprised when the cashier offers to help dress her wounds in the back room.
When Andy asks why the woman is helping a stranger without asking any questions, the woman says that
she expects Andy to pass on the act of kindness to someone else tomorrow, which leaves Andy thinking
about the people she’s lost. In Merrick’s lab, Joe and Nicky are kept strapped down to chairs
while the doctors keep taking samples. Copley points out that Merrick has all the samples he
could ever need so they don’t need to hold the duo hostage anymore, but Merrick says he’ll do
whatever he wants and he won’t stop until he has results. Nicky tries telling the doctor
that people have done the same experiments on them in the past and it's never worked, but the doctor
ignores him. Sometime later in the middle of the night, Nile wakes up from a bad dream and decides
to go outside for fresh air. She finds Andy going through her phone and Nile shares some stories
about her family, but Andy sadly doesn’t remember hers. Soon Booker meets with them to say that he’s
found Copley’s location and they immediately head off. When they arrive at the address,
Booker leaves to scout the area while Andy gives Nile a weapon. However Nile announces she doesn’t
want to help, saying she wants to spend as much time with her family as she can before it's too
late. Andy decides to let her take the car, only asking her to get rid of the rest of the weapons
on the way. Once she’s far enough, Nile opens the trunk and realizes Andy took the wrong bullets
for her weapon. At the facility, Andy and Booker sneak inside and go upstairs to find Copley. They
immediately hold him at gunpoint, but suddenly Booker shocks Andy by shooting her in the side
and restraining her. He explains that he set them up on purpose because he wants Merrick to figure
out some way to kill them so they don’t have to suffer anymore, and Copley wants the cure
that could’ve saved his wife. However when Booker realizes Andy isn’t healing, he starts to panic.
Soon a bunch of guards come in and restrain Andy and Booker so Copley protests, pointing
out that he doesn’t think Andy will survive any tests. However Merrick doesn’t care and
orders the guards to take Andy and Booker to the same testing room where Joe and Nicky are kept,
demanding results. Meanwhile Copley is suddenly cornered by Nile, who demonstrates her powers
so Copley will explain what’s going on. He tells her he’s spent years doing research on the team
and learned about all the good they’ve done for humanity. Copley also says he had thought that by
bringing the team in for this testing he would be helping the world, but he’s realized that he was
wrong. Then Nile convinces Copley to take her to the team. Moments later, they arrive at Merrick’s
building and Copley grants Nile access. She makes it to the upper floors and is immediately shot,
but she quickly recovers and starts making her way through all the guards, killing them until
she finds the right room. Nile frees her friends and tells Andy she’s seen all her work, confirming
she definitely has something to fight for. Nicky and Joe are furious with Booker for his betrayal,
but Andy points out that now isn’t the time to argue about this. Afterward the team moves through
the building fighting guards as they try their best to cover Andy, but she quickly proves that
she’s still just an amazing warrior even if she’s no longer immortal. After they’re hit by a bomb,
Andy beats up a guy until he confesses Merrick’s location. However when they arrive at Merrick’s
office it is empty, and they notice that the elevator is going down. The guys go to chase after
Merrick while Nile stays with Andy. Unfortunately the elevator going down had been a trap, and
Merrick suddenly shows up with an axe. Copying the trick from the plane, Nile pretends to shoot Andy,
who quickly jumps on a distracted Merrick to steal his axe and hit him before Nile tackles him.
They break through the window and land on a car, which kills them both. Soon the guys come to help
Nile out, and once Andy joins them, they leave together before the cops arrive. Sometime later,
Booker waits outside while the team has lunch and discusses what Booker’s punishment will be
for his betrayal. Nile keeps him company and says they’ve been making arrangements to fake her death
and give her family closure, so Booker tells her she will make a great addition to the team. Later
Andy talks with Booker and informs him that his punishment will be spending one hundred years
by himself. Since Andy is mortal now, this means they’ll never see each other again, and
they say goodbye with a hug. Afterward the group confronts Copley to tell him that his punishment
will be working for them by getting them jobs and deleting all evidence of their existence.
Six months later in France, Booker returns to his apartment and is shocked to find Quynh there.
