The plot concerns an alien who takes over the body of an Earthling (a deceased factory worker who is resurrected) in order to learn about The Planet Earth and threatens the human kind.

In the vicinity of the Po the body of the worker Trabucco is found, who everyone thinks dead. But in reality, the body has been occupied by an alien from the planet Ultra, whose inhabitants plan to take over the earth. About to undergo an autopsy, Trabucco-Omicron manages to get the body that contains him into operation. Gradually, by imitation, Omicron simulates the functioning of a human. Endowed with extraordinary new mechanical skills, Trabucco is reinstated in the factory where he worked. He occasionally discovers the place where subversive workers gather, whom he inadvertently denounces. As it begins to regain consciousness, Omicron wants to return to its planet.
