A war is waged between the frost giants and Thor’s homeland. Loki fights for his right to the throne. Thor is cast out of Asgard by his father and sent to 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 a scientist; Jane Foster, and has an affair with her. Thor then battles the evil forces of his brother Loki along with a robotic giant destroyer that attacks a town. The powerful, but arrogant god Thor, is cast out of Asgard to live amongst humans in Midgard (Earth), where he soon becomes one of their finest defenders.
