In Marvel Studios’ „Thor: Ragnarok,” Thor is imprisoned on the other side of the universe without his mighty hammer and finds himself in a race against time to get back to Asgard to stop Ragnarok–the destruction of his homeworld and the end of Asgardian civilization–at the hands of an all-powerful new threat, the ruthless Hela. But first he must survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger–the Incredible Hulk!
Two years after the battle at Sokovia, Thor has been unsuccessfully searching for the Infinity Stones, and is now imprisoned by the fire demon Surtur in Muspelheim. Surtur reveals that Thor’s father Odin is no longer on Asgard, and that the realm will soon be destroyed in the prophesied Ragnarök, once Surtur unites his crown with the Eternal Flame that burns in Odin’s vault. Thor defeats Surtur and claims his crown, believing he has prevented Ragnarök.
