"When we last saw Thor, he was flying off to figure out who was manipulating the Avengers at the end of Age of Ultron. Eventually, he hears rumblings of trouble in Asgard: His evil brother, Loki (Tom Hiddleston), has been impersonating their missing father, Odin (Anthony Hopkins). Loki’s rather lax governing leads to the reemergence of an imprisoned Hela (Cate Blanchett). Thor’s initial encounter with Hela gets him blasted to Sakaar, a barbaric planet ruled by the charming but nefarious Grandmaster (Jeff Goldblum). Valkyrie (Tessa Thompson), a tough, hard-drinking warrior hiding out on Sakaar brings the god to the Grandmaster…Thor is then forced into becoming a gladiator, which leads to his haircut and the loss of his trusty hammer."
