Thor's retirement is interrupted by a galactic killer known as 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.
