Okay, here is a plot summary for the first Spider-Man movie (1990):
Plot Summary: Spider-Man (1990)
Act I: The Origin
The story begins in a science laboratory at the University of Washington. A shy and nerdy high school student named Peter Parker is attending a demonstration involving genetically engineered spiders. During the chaos of a explosion, Peter is bitten by one of the escaped spiders.
While initially experiencing no immediate effects, Peter soon discovers he has gained extraordinary powers: superhuman strength, agility, and the ability to cling to surfaces. He also develops "spider-sense," an intuition that alerts him to danger. Excited by his new abilities, Peter starts using them for personal gain, primarily to impress his crush, Gwen Stacy, and to make money by catching thieves at his Uncle Ben's store.
Meanwhile, Peter's supportive Uncle Ben is being robbed and murdered by two men – the notorious criminals known as the Green Goblin and the Prowler. Shocked and grief-stricken, Peter vows to use his powers to fight crime, driven by the mantra he overhears in a newspaper: "With great power comes great responsibility."
Act II: The Conflict
Peter creates a homemade costume and begins patrolling the streets of New York City as the mysterious vigilante Spider-Man. He successfully stops several crimes, earning praise but also attracting the attention of the police, particularly Detective Tom Riley.
His efforts to fight crime become more serious when the Green Goblin, whose real identity is the eccentric industrialist Norman Osborn, emerges. Using advanced technology and a goblin glider, the Green Goblin starts a series of destructive robberies and attacks, aiming to destroy the city's financial district. Spider-Man finds himself facing his first major adversary.
As the Goblin's threats escalate, Peter's life becomes increasingly complicated. He must balance his secret identity with his schoolwork, his job at Uncle Ben's, and his relationship with Gwen, who is unaware of his true identity but supports him as Spider-Man. Tensions rise when Peter discovers that the thugs working for the Goblin are actually his Aunt May's (Ben's sister) former employees, putting her in danger.
Act III: The Climax and Resolution
The conflict reaches its peak during the annual Oscorp Science Convention, where Norman Osborn plans a major Goblin attack. Spider-Man intercepts the Goblin's glider but is outnumbered. During the fight, Peter is separated from his web-shooters and falls from a great height.
Just as it seems he will die, he is caught by Gwen Stacy, who realizes he is Spider-Man. This revelation puts Gwen in danger, as the Goblin sees her as a threat. In a desperate act to save both Peter and Gwen, Spider-Man uses his webs to catch himself and swing back, but the Goblin throws a bomb that Peter tries to deflect.
The bomb explodes, severely injuring Gwen and knocking Peter unconscious. Norman Osborn escapes the scene, seemingly unharmed but also severely affected by the chemicals, becoming temporarily ill and more unstable.
Spider-Man is taken to the hospital. Gwen, recovering from her injuries, finally understands Peter's secret and embraces him. Peter, seeing the consequences of his inaction (his Uncle Ben's death), fully accepts the responsibility of being Spider-Man and resolves to fight crime, truly embodying the lesson he learned: that great power requires great responsibility. The film ends with Peter looking out over the city, ready to continue his crime-fighting duties.
