The greater the ability, the greater the responsibility. Spider-Man Peter Parker (Andrew Garfield) is fighting crime and disaster with all his strength, and finally welcomes the moment to graduate. But a knot in the past brought his relationship with his girlfriend Gwen Stancy (Emma Stone) to freezing point. Gwen was hired by Osborne Group, which provides electricity to the city. Two incidents occurred during the same period that could not help but influence the fate of this company and Peter and others. Osborne's boss died of illness, and his son Harry (Dane DeHaan) accepted the $200 billion giant at the age of 20. On the other hand, Max Will Dylan (Jamie Foxx), an electrical engineer who greatly admired Spider-Man, died accidentally while repairing the unit. When he woke up again, he found himself a superhuman full of electricity. Feeling deceived, Max and Spider-Man face off in Times Square, and Peter and Harry's friendship will also be teased by fate...
