Due to his insolence, Thor, an arrogant and indifferent god, is exiled from Asgard by his father, Odin, who strips him of his powers and sends him to Midgard, Earth. Now living as Donald Blake, a lame doctor with no memories of being a god, Thor must find his hammer and regain his powers to stop the invasion of Loki, his adopted brother who intends to make Earth his kingdom.
