Thor is the son of Odin ( king of Asgard) and an arrogant God. Loki is this family. For rupturing the armistice between Asgard and Jotunheim, Odin exiles Thor to Earth after stripping him of all the Godly powers. Thor’s hammer, the source of his power, is enchanted similar to that only the good can apply it. Thor gets separated from his hammer. While the hammer is planted byS.H.I.E.L.D, Thor is planted by. Jane Foster and. Erik Selvig. Thor manages to get to the hammer but is unfit to lift it because he’s not good. Back in Asgard, Loki finds out that he’s espoused. While Odin enters his deep slumber, Loki takes over the throne. Thor’s musketeers don’t like this and move the doorkeeper of the Bifröst (rainbow ground transportation thingy), Heimdall, to shoot them to Earth. Loki gets to know of this and sends the Destroyer (an imperishable metallic being thingy) to Earth to kill Thor.
The Destroyer defeats Thor’s musketeers, but he offers himself as immolation and is struck. Because of his good conduct, Thor’s hammer returns to him. Thor destroys the Destroyer and heads back to Asgard to defy Loki. The two of them fight, and Thor blows up the Bifröst ground so that no one can enter Asgard and foray it. Odin awakens and stops Thor and Loki from falling into the emptiness under the ground. Loki commits self-murder by letting himself fall off (no he doesn’t die, he returns in The Punishers). Thor and Odin attune, but Thor is stuck on Asgard. Back on Earth, Jane is looking for a way to get to Thor.
ThorPost-Credits Scene
Nick Fury brings. Selvig to see the Tesseract and says he'd like him to take over Project Pegasus. By now, Loki has figured out that the Tesseract is withS.H.I.E.L.D and has taken control of Dr. Selvig’s mind. We can see Loki prompting Selvig to agree, and he does. Now, though the scene appears at the end, this event happens right in the middle of the film.
