After vanquishing Thanos and renouncing his claim to the Asgardian throne, Thor embarks on a journey unlike anything he's ever faced. But his quest for inner peace is interrupted by galactic killer Gorr the God Butcher, who seeks the extinction of the gods. To combat the threat, Thor enlists the help of King Valkyrie, Korg, and ex-girlfriend Jane Foster, who - to Thor's surprise - inexplicably wields his magical hammer, Mjolnir, as the Mighty Thor. Together, they embark upon a harrowing cosmic adventure to uncover the mystery of the God Butcher's vengeance and stop him before it's too late.
