That night a concerned May speaks with Peter, who assures her hes fine. Peter goes to his room and looks through the photos he managed to get but then, thinking of Harry, decides to delete them, despite May needing the money. He lays down, blaming himself for not saving Emily, believing himself to have been reckless. The next morning, Harry sits in his penthouse, numbly looking out over New York. Norman walks in, and we get a hauntingly chilling scene between the two, where Noman comes off as particularly cold and harsh. Harry angrily shouts at Norman, yadda yadda, drama. Harry doesnt attend school, Norman heads to his office. When he arrives, Norman orders Mendel to find someone to take out Toomes, then refusing to reschedule a meeting with an investor, despite his loss.
After school, Peter manages to track down Sam Wilson, who after the events of Civil War, is hiding out in New York. After a brief moment of hostility, realising that Peter isnt working with Stark on the accords, Wilson agrees to dig out a file on his Falcon suit, revealing that Adrian Toomes designed it, and it was supplied by Oscorp. Peter thanks him and leaves, with Wilson having a little more respect for Spidey now. Meanwhile, at Oscorp, Tony Stark enters Normans office to discuss Normans HAMMER proposal, offering his condolences to Emily, before requesting to withdraw from the project, citing the attack as his reasoning. Stark leaves, and Norman walks over to a photo of Emily, which he looks at intensely for a while. Peter then heads to Oscorp, under the guise of going to see Harry, only to be met by Gwen, who says that Harry doesnt want to see anyone; shes already checked. They part ways, and Peter then sneaks into the Oscorp archives, looking for information on Toomes, only to find his files erased, except for a general employment record: then realising that Toomes is Liz father. On his way out he bumps into Stark, then having to awkwardly explain why hes there. Peter says he believes Toomes work was stolen from him, and that he was the one who attacked Oscorp; an idea which Stark agrees with, saying he already believed that Norman was up to something, then revealing that he just placed a small monitoring device under Normans desk. Mendel informs Norman in his penthouse that he has bailed Herman Schultz out of jail, and offered him a job in return for taking out Toomes.
That night, Spidey heads to Toomes home, where he is frantically packing bags. Upstairs, Manuel is tutoring Liz, and awkwardly trying to flirt. She aint having none of it. Toomes rushes out to his garage, where he finds Spidey waiting for him. The two briefly speak, before Shocker blasts into the garage, taken aback by Spideys presence. In the brief moment of confusion, Toomes flees, and Spidey attacks Shocker, with Shocker deciding to take revenge on Spidey instead of carry out his mission. Upstairs, Manuel and Liz hear the noise, and rush downstairs, only to see Shocker and Spidey smash through a wall into Lizs lounge. Manuel tries to act cool and get Liz to safety, which draws a surprised reaction from Spidey, who briefly mocks him, before being attacked by Shocker. After once again disabling Shockers gauntlets, Spidey swoops around and swings Manuel and Liz out of the house, telling them to call the police, and then telling Liz she deserves better. (Or maybe something less harsh; teasing of Manuel is the key here). Spidey stealthily walks back inside, only to find Shocker is gone. After this, Peter returns home, and sees on the news that Toomes is now publically known as a suspect in the attack.
The next day at school, Liz begins to be bullied by other students for her fathers actions; she sits alone at lunch, and Peter goes over to her. They bond, and we learn here that Liz is actually nicer than we all thought. Peter says he doesnt think Adrian is a bad man; Liz agrees, blaming herself for his actions. MJ comes over and leaves with Liz, smiling at and briefly speaking with Peter. After school, Gwen heads to Oscorp, where she meets with Harry, who finally agrees to see her. The two speak, and Gwen comforts him. Some nice tender scenes here, where we see the two bond. The evening, Norman is shouts at Schultz in his office for failing to take out Toomes. Schultz protests that Spider-Man showed up, and then mentions Toomes daughter interfering which gives Norman an idea. The following morning, Tony Stark arrives at the New Avengers facility, where he checks the recordings from the bug he placed under Normans desk and overhears Normans plan. ****.
We then return to Midtown, where it is the day of the Homecoming dance. The school is all nicely decorated, with the gymnasium set up as the venue. Peter is on the phone with Harry, who says he was sorry he didnt return Peters calls. They talk for a bit before Peter enters his Biology class, and noticing that Gwen is also absent, sits next to Liz. Manuel notices this, but Flash mocks him for losing Liz to the other nerd, shutting him up.
Meanwhile, Adrian Toomes is in his van in an alleyway, looking down-in-the-dumps. Suddenly, he gets a call on his mobile, being told that Liz isnt safe. Immediately, Toomes dives into the drivers seat, and heads to Midtown. At break, Manuel tells Peter to back off of Liz, after which Liz confronts him for being an ***hat. Just as tension builds to a high, Shocker blasts in through a wall, and grabs Liz, firing into the air as he does so, causing the other students to flee. Peter ducks into a closet, quickly changing into his Spidey suit, before crawling through a vent, finding Shocker in the main hall however, before either can attack, Vulture comes crashing into the room, looking pretty angry.
We have a tense standoff before a three-way fight ensues, with Liz eventually being caught by one of Shockers blasts, injuring her. Vulture goes into a frenzy, and starts firing recklessly, eventually sending Shocker flying. Noticing students are still present; Peter swings Vulture into a corridor, where the fight continues. As Shocker gets up, suddenly Iron Man soars into the hall, where he identifies Liz, and asks where Spidey and Vulture went. She points to the hallway, when Shocker suddenly fires at Stark, not wanting to lose his employment opportunity. As Spidey and Vultures fight continues, blasting through classrooms, Spidey tries to reason with Toomes, but Toomes believes him to be sent by Osborn too. They eventually crash into the gymnasium, smashing through tables and Homecoming decorations. Liz hurriedly follows them, witnessing the fight. Toomes notices her, and tries to dispatch Spidey, eventually slicing his mask. Liz shouts at Toomes, breaking him out of his frenzy, after which he explains that he didnt do anything to be bad; he wanted to protect his job to continue to support her. After seeing the damage he caused, Toomes stands down, and Liz hurries over to an injured Spidey, seeing his face, discovering that Peter is Spider-Man. In shock, she hugs Peter, who jokingly asks her to the dance; Liz says she cant say no to Manuel, despite everybody hating him at this point, but then saying she thought Peter already had a date. Peters confused, but before he can say anything, Stark enters with Shocker swung over his shoulder, briefly complimenting Peter, who puts on whats left of his mask and swings away, taking Liz to safety outside. Manuel hurries into the Gym, only to be made fun of by Stark usually you save the girl before the fights over, kid. Peter quickly changes, and snaps a photo of Stark and Shocker outside, which Stark throws up a peace sign for. Peter asks Liz to keep his identity secret; she agrees, and thanks him.
That afternoon, at Oscorp, Stark confronts Osborn, threatening to expose his actions. Norman threatens Stark back with secrets from Starks past, and then shows Stark his bug. Stark agrees to forget about it, asking Norman to restore Toomes credit on the HAMMER project, in return for his re-investment. As he goes to leave, Stark suddenly turns, and asks one more thing: make Peter be the one to get Connors internship. Peter returns to the Bugle, where he presents Jameson with the photo of Stark and Shocker, which he agrees to buy. An impressed Robbie remarks that he told Jameson that kid has potential. Toomes and Schultz are placed into cells at an NYPD station. At Oscorp, Gwen is still with Harry. She asks if he wants to go to the dance; he says no, and that hed rather stay there. Gwen asks if hell dance with her there, and he agrees. We have a nice aww moment here, and we see Harrys phone ring in the background its Peter, although they dont notice the call.
That night, Peter gets ready for the dance, which has been moved to the town hall at the last minute, thanks to a favour called in by Tony Stark. He again expresses concern about going with Miss Wonderful Personality, before the doorbell rings. Aunt May calls for Peter to open the door, and he slowly comes downstairs. Hesitantly, he opens the door and to his shock, MJ is standing there. Taken aback, Peter goes to speak, but barely manages a voice crack, whilst MJ smiles, and says: "well Petey, looks like you just hit the jackpot". We end on MJ smiling, and then cut to the credits.
In a mid-credits scene, Norman arranges with Stromm for Toomes and Schultz to be transferred to the Oscorp-founded Ravencroft Institute after their trials, so as to keep a closer eye on them. He opens up a file, and then states he cant risk further interference with his plans.
