Imprisoned on the other side of the universe, the mighty Thor finds himself in a deadly gladiatorial contest that pits him against the Hulk, his former ally, and fellow Avenger. Thor's quest for survival leads him in a race against time to prevent the all-powerful Hela from destroying his home world and the Asgardian civilization. Without his powerful hammer, Thor must find a way to escape his captors and return to Asgard before it's too late. Interwoven with Thor's story are cosmic encounters and a journey of self-discovery as he struggles with the responsibilities of leadership and his place in the universe.

Thor's journey is wrapped in the complications arising from his mischievous brother, Loki, whose allegiance is as uncertain as ever. Together, and with the help of new and old allies, they must navigate a universe full of danger and deception. The lingering threat of Hela, the formidable Goddess of Death, looms over Asgard, while Thor grapples with the prophecy of Ragnarok, the prophesized end of his world. Amidst the chaos, moments of humor and new relationships shape Thor's path, as he sets out to redefine his legacy and confront a future that is anything but certain.
