After helping Tony Stark, the teenage Peter Parker returns to his life in Queens, New York, yearning for more action as Spider-Man. While navigating the trials of high school and the awkwardness of adolescence, Peter is eager to prove himself worthy of being more than just a neighborhood hero. He wants to become an official part of the Avengers, but Stark advises him to keep his superhero activities low-key and to focus on being a friendly neighborhood Spider-Man. Despite this, Peter can't help but look for bigger threats to prove his abilities, driven by the thrill of his past experiences with the Avengers.

Peter's ordinary life is upended when he encounters a group of criminals with advanced, weaponized technology salvaged from the aftermath of the battles between the Avengers and their enemies. These criminals, led by a man outfitted in a vulture suit made from the same alien technology, are committing high-tech heists and pose a threat to the city. Peter sees this as his opportunity to show his worth to Stark and the Avengers and begins his own investigation into their operations. In his zeal to take on this new adversary, Peter starts to bite off more than he can chew, struggling to balance his dual life as a student and a burgeoning superhero.
