The film opens in space as the Asgardian evacuation ship has come under attack by the Mad Titan
Thanos He and his minions the Black Order – Cull Obsidian Proxima Midnight Ebony Maw
and Corvus Glaive– walk among the corpses of nearly all the slain Asgardians Thanos
faces Loki and demands the Tesseract or else he will kill Thor Thanos already has the Power
Stone in the Infinity Gauntlet after taking it by force from Xandar Loki lets Thanos go
ahead to kill Thor but he relents and presents the Tesseract However the Hulk attacks Thanos
and gets in a few good punches before Thanos stops going easy and pounds the Hulk into
the wall Heimdall uses the last of his powers to send Hulk through the Bifrost down to Earth
Thanos then impales Heimdall through the heart Loki then appears to surrender to Thanos and
join him but he instead makes a futile attempt to kill him Thanos grabs Loki by the throat
and squeezes until he crushes Loki’s neck killing him as Thor can only watch in anguish
Thanos cracks open the Tesseract to get the Space Stone and he and his children leave
Thor crawls over to Loki’s body as the ship explodes
Hulk crashes into the Sanctum Sanctorum in New York City as he transforms back into Bruce
Banner He is found by Doctor Stephen Strange and Wong Bruce warns them that Thanos is coming
Tony Stark and Pepper Potts are out for a jog as Tony mentions having a dream that he
and Pepper were going to be expecting a child Pepper herself doesn’t seem ready for that
Strange then enters through one of his portals and tells Tony he needs to talk to him and
he brings Bruce out to stress how urgent the matter is
Tony goes to the Sanctum Sanctorum where Wong explains the history of the Infinity Stones
(Power Space Soul Time Reality and Mind) and why Thanos might want to get his hands on
them Tony realizes he needs help but he tells Bruce how complicated it is after the Avengers
broke up Moments later a ship starts hovering over the city Peter Parker is on a field trip
when his spider senses tingle and he realizes trouble is afoot He uses Ned as a distraction
so he can head out as SpiderMan Maw and Obsidian find Tony Bruce Strange and Wong as they attempt
to take the Time Stone from Strange Tony gets his Iron Man armor to fight while Strange
and Wong use their powers as well Maw is telekinetic so he is able to deflect any attack toward
him Bruce tries to Hulk out but he cannot Spidey joins the fight as they take on Obsidian
Wong manages to send Obsidian through a portal (and also slice his arm off as he tries to
jump back before it closes) Maw makes a grab for the Time Stone but Strange has placed
an enchantment on it that prevents him from grabbing it He takes Strange with him so Spidey
jumps onto Maw’s ship Iron Man flies up after him and sends the Iron Spider armor
to protect Peter but also send him back to Earth Instead Peter manages to stow away onto
the ship Wong stays to guard the Sanctum while Bruce decides to call the rest of the Avengers

In a flashback a young Gamora is on her home planet as she is separated from her mother
in the middle of Thanos’s invasion Thanos takes Gamora with him and presents her with

if he were to find out from her she asks Quill to kill her They make it to Knowhere and find
Thanos interrogating Tivan the collector to the Reality Stone’s whereabouts Drax is
ready to storm in but Mantis puts him to sleep Gamora leaps in to stab Thanos in the neck

to be an illusion from Thanos to see that she did care He already has the Reality Stone
and was playing a trick on her Thanos takes Gamora as Quill attempts to intervene Drax
and Mantis get messed up with the stone’s power Gamora pleads with Quill to kill her
but Thanos turns Quill’s gun to bubbles before taking Gamora with him
Peter and Tony meet as they try to help Strange who is trapped and tortured by Maw until he
gives up the Time Stone Peter devises a plan inspired by the movie “Aliens” in which
Tony blasts a hole through the ship to suck Maw out into space where he freezes up Strange
is nearly sucked out until Peter saves him and Tony closes the hole up The three join
forces to stop Thanos and Tony “officially” makes Peter an Avenger
Thanos knows that Gamora found out where the Soul Stone is despite her denying it In order
to get it out of her he shows her that Nebula is being tortured by having her body split
into pieces Thanos uses Nebula’s memory logs to reveal that Gamora knew about the
Soul Stone’s whereabouts because she found a map to it but she burned it As Thanos hurts
Nebula more Gamora relents and admits it’s on the the planet Vormir Thanos travels there
with Gamora and Nebula manages to escape by killing a guard and sending a call out to
Mantis to meet on the planet Titan
On Vormir Thanos and Gamora meet the keeper of the Soul Stone…THE RED SKULL He was teleported
to the planet via the Tesseract and learned that the stone may only be obtained through
sacrificing a loved one Gamora laughs since she believes that Thanos loves nobody and
therefore cannot gain the stone but Thanos sheds a tear because he truly does love Gamora
and says he cannot give up what he wants a second time Gamora tries to kill herself with
the dagger but Thanos turns it into bubbles He grabs Gamora and with a heavy heart he
throws her off a cliff Thanos is momentarily transported to a realm where he finds the
Soul Stone in his hand

Tony Peter and Strange arrive on Titan and come across Quill Drax and Mantis They briefly
fight after thinking the other one is working for Thanos until they realize he is a mutual
enemy They try to come up with a plan to take down Thanos but Strange uses the Time Stone
to view millions of different outcomes in which they fight Thanos and he says there
is only one in which they win
Thor tries to get the rings on Nidavellir turning even having to turn the beam on himself
which causes severe damage to his body Eitri uses the metal to forge the weapon while Groot

planet with little to go around for its people His resolution was genocide across multiple
planets which he called “mercy” The heroes ambush Thanos in an attempt to remove the
Gauntlet from his hand Nebula arrives after crashing into Thanos Mantis has her hold on
Thanos to subdue him but she can’t knock him out because he is too strong Tony Peter
and strange attempt to remove the Gauntlet until Quill asks where Gamora is Mantis reads
that Thanos is mourning and Nebula surmises that Thanos killed Gamora Quill becomes enraged
and starts hitting Thanos breaking Mantis’s hold and ruining the plan Thanos uses the
Gauntlet to destroy one of Titan’s moons and hurl it toward the heroes Tony engages

mechanism that crushes her Glaive attempts to go after Vision only to get impaled by
his own scythe by Vision himself
The Mad Titan then arrives in Wakanda Despite their combined efforts the Avengers can barely
touch him Steve attempts to take Thanos on but is taken out with a swift punch Wanda
reluctantly uses her powers to destroy the Mind Stone and Vision as he declares his love
for her However Thanos uses the Time Stone to reassemble Vision just so he can tear the
Mind Stone from his head and kill him for good With that Thanos has every Infinity Stone
Thor leaps into the air and impales Thanos with Stormbreaker but it is nonfatal and Thanos
then snaps his fingers
Thanos finds himself in another realm where he sees young Gamora She asks him if he succeeded
and what it cost He says everything Back in the real world the Gauntlet is fried but the
stones remain intact He disappears before Thor’s eyes Suddenly Bucky starts to crumble
to dust in front of Steve The same starts to happen to TChalla Sam Wanda and Groot as
well as most of the Wakandan army On Titan Drax Mantis and Quill start to disintegrate
Peter slowly dies in Tony’s arms Strange follows suit Tony and Nebula are left alone
