A war is waged between the frost giants and Thor's (Chris Hemsworth's) homeland. Loki (Tom Hiddleston) fights for his right to the throne. Thor is cast out of Asgard by his father Odin (Sir Anthony Hopkins) and sent to Midgard (Earth) as punishment for his arrogance and disobedience in his battle. He loses his powers of the hammer until it returned to him on Earth and he pulls it from the ground. In his fight for his own freedom on Earth, he meets scientist Jane Foster (Natalie Portman), and falls in love with her. Thor then battles the evil forces of his brother Loki along with a robotic giant destroyer that attacks a town.
