Thor is imprisoned 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 civilisation, in 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!
