Plot
Having survived the vacuum of space after the Statesman's blast, Thor is rescued by the Guardians of the Galaxy, who received the Asgardians' distress call. They take him aboard the Benatar, where Thor tells of how Thanos killed half the Asgardians to obtain the Space Stone and decimated Xandar to obtain the Power Stone. Gamora recounts how Thanos traveled from planet to planet, killing half the population of each, and will do the same to the entire universe should he complete the Gauntlet by merely snapping his fingers.

They figure that Thanos will be headed to Knowhere in order to take the Reality Stone from the Collector. Thor decides to leave for Nidavellir, as he intends to ask Eitri to craft him a new weapon. Thor leaves with Rocket Raccoon and Groot while Star-Lord, Gamora, Drax the Destroyer and Mantis depart for Knowhere.

Meanwhile, Proxima Midnight and Corvus Glaive, two more of Thanos' children, ambush Vision, who attempts to live a normal life with Wanda Maximoff in Scotland. Vision is deeply weakened in the attack, while Maximoff barely manages to hold her own against both assailants. However, reinforcements arrive in the form of Rogers, Falcon and Black Widow, who have been contacted and filled in by Banner. Together, they force Proxima Midnight and a heavily wounded Corvus Glaive to retreat before returning to the New Avengers Facility.

Remembering how Thanos destroyed half of her people and adopted her in the process, Gamora makes Quill promise that he will kill her if she gets captured by Thanos. Although Quill is reluctant, Gamora makes him promise and swear on his mother. He eventually agrees, and the two share a kiss. As they arrive on a deserted Knowhere, the Guardians of the Galaxy witness Thanos violently interrogating the Collector over the location of the Reality Stone. Unfortunately, the group makes too much noise and Thanos realizes their presence. Gamora goes on the offense, attacking and promptly defeating the Titan, who falls to the ground, seemingly killed.

However, the group discovers that Thanos has already acquired the Reality Stone, and has been using it to cast a massive illusion. He drops the illusion, revealing a burning Knowhere and himself, alive and well. Thanos had expected Gamora to come and fight him, and is aware that she is the only person who knows the location of the elusive Soul Stone. Thanos easily subdues Gamora and incapacitates Drax and Mantis. Quill aims to fire at Thanos' head, but Gamora begs Quill to keep his promise and kill her, with Thanos pushing Gamora against the gun, inviting him to do so. Despite his heartbreak, Quill pulls the trigger, only for the gun to shoot harmless bubbles, thanks to the Reality Stone. Thanos then teleports away with Gamora.

Back at the facility, James Rhodes discusses recent events with Thaddeus Ross, who is outraged at Vision's recent disappearance. Rhodes counters that Vision is only missing because of the Sokovia Accords, which even he now regrets signing. Rogers, Wilson, Romanoff, Vision, and Maximoff arrive, and Ross demands they all be arrested. Rhodes cuts his transmission off, an act which will likely end his military career, and greets his old teammates.

Banner emerges as well, sharing a brief reunion with everyone. After bringing everyone up to speed, Banner suggests calling in Hawkeye for help, but Romanoff explains that he as well as Scott Lang are unavailable, having surrendered themselves to the US government, making deals to be placed under house arrest with their families. Together, the team decides that the Mind Stone must be destroyed and that Maximoff is the only member powerful enough to do so. However, in order to destroy the stone without killing Vision, Rogers suggests traveling to Wakanda. In Wakanda, T'Challa and Okoye deliver a new vibranium arm to Bucky Barnes, who has recovered from his mental programming.
