Enredo

When New York is put under siege by Oscorp, it is up to Spider-Man to save the city he swore to protect as well as his loved ones.

We've always known that Spider-Man's most important conflict has been within himself: the struggle between the ordinary obligations of Peter Parker and the extraordinary responsibilities of Spider-Man. But in The Amazing Spider-Man 2, Peter Parker finds that his greatest battle is about to begin. It's great to be Spider-Man. For Peter Parker, there's no feeling quite like swinging between skyscrapers, embracing being the hero, and spending time with Gwen. But being Spider-Man comes at a price: only Spider-Man can protect his fellow New Yorkers from the formidable villains that threaten the city. With the emergence of Electro, Peter must confront a foe far more powerful than he. And as his old friend, Harry Osborn, returns, Peter comes to realize that all of his enemies have one thing in common: Oscorp.—Sony Pictures Entertainment

Fighting crime and protecting New York City is a dangerous full-time job, and Peter Parker, two years after his battle with mega-criminal Lizard in O Espetacular Homem-Aranha (2012), finds himself bound by his promise to Stacy's late father. Struggling to stand by his word, in the meantime, as Peter's old friend Harry Osborne inherits Oscorp Industries and a deadly retrovirus from his father, a tragic accident gives birth to a new super-villain: Electro, the human power plant. But with the emergence of the unstoppable Green Goblin, the stage seems set for the ultimate confrontation--a fight that could forever alter the course of Peter Parker's life. Can Spider-Man avert the rise of Electro and get the girl?—Nick Riganas

Peter Parker's best friend Harry Osborn returns to New York with a terminal illness. Harry believes the only thing that can cure him is Spider-Man's blood. When Spider-Man refuses Harry turns to the world's newest villain Electro to seek revenge

Former Oscorp scientist Richard Parker records a video message to explain the circumstances behind his disappearance. While attempting to flee with his wife, Mary, aboard a private jet, they are confronted by an assassin sent to retrieve Richard's research. A struggle ensues, and the jet crashes, killing both Richard and Mary.

In the present, two years after defeating Dr. Curt Connors, Peter Parker continues his crime-fighting as Spider-Man. While apprehending Russian criminal Aleksei Sytsevich, Peter grapples with his promise to Gwen Stacy's late father to stay away from her for her safety. After their high school graduation, Gwen decides to end their relationship, sensing Peter's lingering doubts.

Meanwhile, Peter's childhood friend, Harry Osborn, returns to New York to visit his dying father, Norman Osborn, the CEO of Oscorp. Norman reveals that his terminal illness is genetic and warns Harry that his symptoms will soon develop. Following Norman's death, Harry is named Oscorp's new CEO.

At Oscorp, electrical engineer Max Dillon, an isolated and awkward employee, suffers an accident when he falls into a tank of genetically engineered electric eels. The incident transforms him into a living generator of electricity. Unaware of his powers, Max, now calling himself "Electro," wanders into Times Square, causing a massive power outage. Spider-Man intervenes, subdues Electro, and has him sent to the Ravencroft Institute, where Dr. Ashley Kafka begins studying him.

As Harry starts exhibiting symptoms of his inherited illness, he deduces from his father's research that Spider-Man's blood might cure him. Harry pleads with Peter to help him contact Spider-Man. Torn by the risks of a transfusion, Peter, as Spider-Man, refuses, fearing it might worsen Harry's condition. Furious, Harry lashes out. Adding to his troubles, Oscorp's vice president, Donald Menken, frames Harry for covering up Electro's accident, ousts him as CEO, and seizes control of the company.

Desperate for revenge, Harry teams up with Electro, who agrees to help him infiltrate Oscorp in exchange for freedom. Together, they kill Dr. Kafka and take back the company. Harry discovers a hidden supply of venom from Oscorp's genetically engineered spiders and injects himself with it. The venom accelerates his illness, mutating him into a goblin-like creature, but an armored suit restores his health and enhances his strength.

Meanwhile, Peter uncovers Richard Parker's hidden lab in an abandoned subway station. He learns that Richard fled because he refused to let Norman Osborn weapons his research. Peter also discovers that Richard used his own DNA in the creation of the genetically engineered spiders, making their effects unique to Peter and preventing Oscorp from recreating the experiments.

Afterward, Peter reconnects with Gwen, who reveals she has been offered a scholarship to Oxford University. Peter confesses his love for her, and they decide to move to England together.

Electro, seeking vengeance, causes a massive blackout across the city. Peter and Gwen work together to restore power and overload Electro's energy, killing him. However, their victory is short-lived when Harry, now the Green Goblin, arrives and kidnaps Gwen after deducing Spider-Man's true identity. Taking her to the top of a clock tower, Harry taunts Peter and drops Gwen. Though Peter subdues the Goblin, he fails to save Gwen, who falls to her death. Devastated and guilt-ridden, Peter abandons his role as Spider-Man.

Five months later, Harry, imprisoned at Ravencroft, begins recovering from his transformation. He conspires with his associate, Gustav Fiers, to assemble a team of villains, starting with Sytsevich. Outfitted with an electromechanical suit of armor, Sytsevich dubs himself the "Rhino" and wreaks havoc in the city. Inspired by Gwen's graduation speech, Peter rediscovers his purpose and returns as Spider-Man to confront the Rhino, ready to embrace his responsibility once more.
