The Vulture, a man-bird villain, possesses an electronic device inducing huge flocks of birds to join him in attacking New York City. Unless the mayor bestows to the Vulture 2 million dollars, the Vulture promises to continue his reign of terror from the sky. Scientifically astute and resourceful Spidey drops a device that disrupts the bird-controlling transmissions, onto the Vulture's head, and provokes the bird-man into giving to the birds the attack signal, which causes the confused birds to attack the Vulture and force the flying criminal to flee, without the 2 million dollars that he tried to extort.
