Description
Rocky Foscoe is a Chicago barber. One night he drives the long way home and, while parked on Old Orchard Road, has a nightmare in which his car is hovering in mid-air. The next day, he consults a doctor about his experience. He tries to return to work, but has an anxiety attack and flees, which worries his mistress.
He returns to the road to make sense of his experiences. An old man offers him help, and comments that strange things have been happening on that stretch of road; he himself had heard screams coming from the sky, implying that Rocky's car actually did float in the air. Soon afterwards, Rocky has another attack; in return, his host fires at him with a shotgun, and Rocky reacts by killing him with supernatural force.
Five hours later, Chicago police discover the body of the old man, and tire tracks from Rocky's car that suddenly stop, as if his car had floated into the air. That night, seeing an item in the newspaper about the old man's death on the road, the doctor connects Rocky with the killing and calls the police. Later, Rocky unexpectedly shows up, discovers the doctor's suspicion, and kills him with his psychic powers. When the police arrive, they surmise a supernatural explanation for the killing. The next day, they consult a professor at the Chicago Institute of Psychology, who explains his parapsychological theory that the killer has somehow tapped the latent power of his subconscious mind, which he refers to as "psychotronic energy".
Rocky visits his mistress and returns home. A confrontation with his wife grows out of hand, and he kills her with his psychotronic powers. The police, on stakeout outside his home, hear the scream and go in pursuit. Rocky drives downtown and manages to keep ahead of the police, at one point using his powers to float the car again. When he reaches a dead end, he crashes the vehicle and flees on foot. He takes the gun from an officer who has trapped him in a warehouse, then heads for the roof of a hotel, killing a security guard on the way. The pursuers catch up with him in a boiler room, but he psychotronically kills one of them (the officer he had taken the gun from earlier) and escapes to a tower in an adjoining building. The police, on the rooftop opposite, call in a SWAT team to shoot down Rocky.
As the SWAT team moves into position, a special intelligence agent appears and orders the police to capture Rocky alive, so his unique powers can be exploited for national security. The sheriff bluffs to Rocky that he has one last chance to surrender, then has him shot. Although he falls off the tower, his body is absent on the streets below. In the final shot, Rocky is back in the woods of Old Orchard Road, his eyes aglow with psychotronic power.
