Thor, an Asgardian god, is a bit too arrogant for his title, and his father casts him out of his home world to live among the humans. There, he meets Jane, a gifted scientist, and falls in love with her - madly. She teaches him how to trust others and depend on those he loves. Thor enjoys the life on planet Earth right until the moment a dark villain from his realm attacks his new home. It turns out to be his brother, Loki, and Thor uses his newly-found strength and the mighty hammer to crush his enemies and bring the traitor to justice. He returns to Asgard as a hero and is greeted both by his old friends and his father - Odin.
