Thor (Chris Hemsworth, The Avengers), prince of the kingdom of Asgard, is a powerful and arrogant warrior whose recklessness triggers ancient quarrels in the domain. For this reason, his father Odin sends him to planet Earth as a punishment so that he can live as a human and discover the value of humility. When the evil villain Loki, the most dangerous villain in the universe, tries to invade Earth, only a person with superhuman strength will be able to confront him. Thor will be forced to fight and learn what it means to be a real hero. All this is complicated when his life as a man is linked to that of a beautiful scientist, Jane Foster (Natalie Portman, Black Swan).
