After being defeated by the Avengers and put in an Asgardian prison, Loki is set free by Amora aka the Enchantress who helps him escape but while escaping she loses control of her magic, and it sends them into the Micro-verse which is like the Quantum Realm from the MCU but in the comics. Once in there Loki and Enchantress's magic are gone and they have to find a different way out and eventually stumble upon Reed Richards who was doing an experiment to explore this place, but he and three others got stuck. Reed takes them back to camp where Johnny Storm, Sue Storm, and Ben Grim are all waiting. Loki asks how to get out and Reed says they're building a machine that can let them escape using Pym Particles that were used in the experiment. Eventually the six come across an old man begging for help and says his name is Nathan. Loki doesn't trust the man, but Reed agrees to help him. The man says years ago he was an astronaut whose ship crashed and the amount of energy from space sent him down here. The movie goes on with them building the ship until Loki finds out that the man isn't what he seems while overhearing the man talk to someone named Ravonna on a transponder. The movie ends with a fight between the man and Loki as they finally become big again. The man looks at them and reveals that he is named Kang and is now free. The post credits scene shows that Reed, Sue, Ben, and Johnny all got powers from the Micro-verse.
