Without any warning, U.S. Army pilot Captain Colter Stevens wakes up on a Metra commuter train en route to Chicago. He is a bit confused because the last thing he can remember is himself flying on a mission in Afghanistan. Even stranger, everyone around him fails to recognize him, believing him to be a schoolteacher named Sean Fentress. Before he can truly get his bearings, the train explodes, leaving no survivors.
Many months have passed since the Battle of Earth. One of the conflict’s participants, Peter Parker, better known as Spider-Man, has attempted to move on with his life to the best of his ability. During this time, he begins harboring feelings for a classmate named Michelle Jones, though she prefers to go by MJ. His school has organized a two-week summer trip to Europe, which Peter sees as the perfect opportunity to confess his feelings. Unfortunately for him, he may find a relaxing getaway is not in his future when he receives a phone call from Nick Fury.
