 After the events of Avengers Endgame, Thor now sets off on a personal journey of discovering who he is, through his inner peace. But now Thor is called back into action once more when he takes on a deadly new adversary named Gore the God Butcher, who seeks the extinction of all the gods. To face this new foe, Thor teams with Korg, Valkyrie, and his old flame Jane Foster. The film opens with Gore, the last of his people, spends his days striving to survive on a barren desert with his daughter, Love. He prays to his god Rappu for help, but Love soon dies of starvation. Just as he begins to hear a voice calling out to him in the distance, Gore discovers an oasis where he finds Rappu, who had killed the latest wielder of an ancient weapon known as All Black, the necrosword. Rappu makes fun of Gore for his helplessness and refuses to provide any assistance. Gore is the last of Rappu's disciples, and he begs the god for help. Rappu coldly shuns Gore, and Gore renounces him. Gore is then called upon by the necrosword, a weapon that can kill gods and was just taken from another being that tried to kill the gods. Gore accepts the necrosword's call and slays Rappu. He then vows to kill every last god. Korg tells a group of Asgardian children the legend of Thor. He was raised in battle and became a legendary hero, saving the world many times but also losing many people close to him, like his mother Friga and, of course, Loki. Thor continues his adventures with the Guardians of the Galaxy, responding to distress calls across the universe while working to get back in shape. However, Thor remains discontent with where he is in life, and intends to retire. Thor and the Guardians arrive at a planet overrun by birdlike invaders. Thor wields Stormbreaker and flies into battle, with the Guardians doing some shooting and heavy lifting as well. After Thor wrecks all the invaders and their ships, the king of the land gifts Thor and the Guardians with two giant screaming goats. As the team flies away and tries to tame the goats. An influx of distress calls regarding Gorg emerge, one of them being from Sif, who had hunted him down. Thor and Korg respond to Sif's call, parting ways with the Guardians who leave to respond to the others. He takes Korg and uses Stormbreaker's power to open the Biverston travel to Sif's location. Thor and Korg come upon an icy land where they find the skeleton of a creature called Fallager. They find a defeated Sif with her arm missing, thinking she is ready to die. She tells Thor about Gorg, and how he is going after the gods, earning him the name God Butcher. Sif warns them that Gorg will attack New Asgard next. Meanwhile, Dr. Jane Foster undergoes treatment for stage 4 cancer. Efforts to research for a cure-proof futile and she beings to lose hope, but Foster becomes inspired to travel to New Asgard in hopes that their magic can help eliminate the cancer. In New Asgard, Valkyrie is ruling as king, and the place has become a tourist attraction, complete with their own theater troupe of actors re-enacting Thor's adventures. Jane goes to a museum where the broken pieces of Mjolnir are left on display. The pieces then appear to glow and react in Jane's presence. As Thor has unknowingly enchanted Mjolnir to protect Foster while they were together, Mjolnir becomes drawn to her presence, fusing itself back together and imbuing her with the powers of the mighty Thor. That night, Gorg uses the necrosaur to swarm New Asgard with Shadow Monsters. Thor also teleport back to New Asgard, where Gorg and his minions, Black Berserkers, are attacking the Asgardians. Thor uses Stormbreaker to smash down the monsters, while Gorg gets sift to safety. In the middle of the battle, Thor is elated to see Mjolnir coming his way, until it returns to Jane, who is now wearing armor as the mighty Thor. Thor is astonished to see her there. While they were able to repel the monsters, Gorg escapes with Asgard's children, including Heimdall's son, Axel. Later, the heroes receive a projected image from Axel. With Thor's help, he is able to show Thor that the kids are being kept in the Shadow Realm. Knowing that Gorg's strength would be at its peak there, Thor, Foster, Valkyrie, and Gorg travel to Omnipotence City to warn Zeus about Gorg, and ask for an army to help fight him. Gorg continues his story with a brief flashback to Thor and Jane's relationship. After their previous adventures, they started a serious relationship, but due to Thor's heroics and Jane's studies in science, they couldn't make the relationship work, so they had to break up. The team reaches Omnipotence City, where all kinds of gods gather. The four disguise themselves and sit as they watch Zeus make a grand entrance, as Thor cites Zeus as an inspiration. However, Zeus quickly proves to be nothing but a jerk who is interested in orgies and not the well-being of the gods. Unconvinced that Gorg is a threat to Omnipotence City. He catches Thor and exposes him, literally, rendering him naked, forcing the other three to reveal themselves. Thor tells Zeus and the gods about Gorg and his threat to go after all of them. But while Zeus quietly acknowledges the danger that Gorg poses, he tells Thor he cannot be bothered to help, or even lend them his lightning bolt to help. Zeus also says that Gorg will not reach eternity, which Valkyrie tells Jane is a cosmic being that can grant a wish to anyone that summons it, meaning Gorg will use his wish to kill all the gods at once. Gorg and his friends fight against Zeus's guards. In the scuffle, Zeus uses his thunderbolt to destroy Gorg's body, only his face remains intact, although this is enough for him to survive. Enraged, Thor uses the thunderbolt to impale Zeus in the chest, which Valkyrie steals as the group escapes to confront Gorg in the shadow realm. On the way, Thor learns of Foster's cancer diagnosis, and the two rekindle their relationship. Thor sees that Stormbreaker is apparently jealous of the attention that Thor has been giving to Jane, prompting him to reassure the Axe that they are still a pair. The ship then makes it to the shadow realm, where everything is stripped of color. Jane hurls Stormbreaker into space because she knows that Gorg will use the Biverse to find eternity. There they attempt to locate the children, only to realize that they had fallen for a trap. Gorg intended to take Stormbreaker in order to utilize the Biverse bridge to access eternity, where he can wish for the extinction of the gods. They battle Gorg and his shadow monsters once more, but are forced to flee back to New Asgard once Valkyrie and Foster are weakened. Thor grabs the Axe and opens the Bivrist, attempting to escape with Jane and Valkyrie. But Gorg catches Stormbreaker just as they are teleported, before Stormbreaker can be transported across the Bivrist. Jane is left without her armor and has gotten weaker and more sickly. Jane is brought to a hospital, where Thor learns that her prolonged use of Mjolnir is killing her faster. Although she wants to help Thor fight Gorg, he tells her that he loves her and wants her to still be alive. She relents and lets Thor go off on his own. Valkyrie is also unable to continue fighting, leaving the Thunderbolt in Thor's possession so that he can fight Gorg again. Gorg brings the children to eternity, where he places Stormbreaker down, and begins opening Eternity's gate with it. Thor arrives and battles Gorg with all his might, but Gorg begins to overpower him. Jane senses this and wields Mjolnir one more despite her weakened condition and join the fight against Gorg, pummeling him and helping Thor free Stormbreaker. Gorg also grants the children temporary powers to use their own weapons to fight the Black Berserkers. With their combined forces, Thor gives Foster ample time to use Mjolnir to shadow the Necrosword into pieces, dooming herself and Gorg. Thor recovers Stormbreaker and has the children use it to return home. However, the gate to Eternity has been open. But they could not stop Gorg from entering Eternity. Thor calls out to Gorg and pleads for him to choose love over death as he rushes to Foster's side. Gorg tells him that he doesn't want revenge, but rather love. Thor chooses love instead of fighting Gorg since he would rather spend his final moments with Jane, who is dying. Gorg is faced with the realization that he is dying due to his prolonged corruption from the Necrosword, and he uses his wish to see his daughter one last time. Thor stays by Jane's side, reaffirming their love for one another and sharing one last kiss as her body disintegrates. Gorg spends one final moment with his daughter. Gorg accepts Gorg's request to take custody of love before he dies from the Necrosword's curse. In the aftermath, a statue of Foster as the mighty Thor is erected in New Asgard. Gorg ends his story by saying that Jane's sacrifice made her a hero and a Skardian legend. Valkyrie went back to ruling New Asgard, using Sif's help to train the children in self-defense. Gorg got his body back and found a male partner from his species. Thor is now raising Gorg's daughter as his own, calling her love, and she is shown to be just as tough as he is. They go outside their home to face an incoming threat together, entrusting her with Stormbreaker while he wields Mjolnir into battle. The two begin traveling the galaxy offering assistance to whom ever needs it. With Gorg saying they are known as love and thunder. In a mid-credits scene, Zeus is revealed to still be alive, and he is plotting revenge against Thor. He turns this task over to his son, Hercules. In a post-credits scene, Foster arrives at the gates of Ohala, where Heimdall welcomes her and thanks her for helping save his son.
