Anne (ALEX DATCHER) is a working woman in her mid-twenties who is trying to put herself through college. On a stretch of desert highway at an isolated gasoline service station, she meets with the attendant on duty, Bill (ROBERT CARRADINE), for a new job as a late-night booth operator. It is not the best night to start. Police reports indicate a homicidal maniac serial killer on the loose.

Bill carefully outlines Anne’s duties. She will be alone, operating from inside the locked booth. The pumps are automated. There is a bathroom inside the booth.

Later, Anne is approached for cigarettes by a lecherous, pasty-faced man (WES CRAVEN) who won’t go away. She is momentarily saved by a good-looking gas customer named Pete (DAVID NAUGHTON) in a sports car. When he forgets his credit card, she runs after him only to lock herself out of the booth. Anne’s problem is compounded when an assorted group of strangers arrive, including a shaggy-haired man who needs to use the bathroom and a couple (PETER JASON, MOLLY CHEEK) who want gas. But someone else is lurking in the shadows off the station’s grease racks.

Could it be the serial killer? Or is it another one of those creepy strangers who seem to be flocking to the gas station’s neon sign like moths to a 100 watt light bulb? Only your Coroner host knows the answer, and he’s not talking… yet!

Richard Hill (STACY KEACH) is a financial analyst in his mid-thirties. He is handsome, well-built and financially secure. He has a beautiful girlfriend named Megan (SHEENA EASTON). His life would be complete… if only it weren’t for his receding hairline.

Impossibly vain, Richard has tried everything for hair restoration. Ready to give up, he takes one last chance with the Hair Today Growth Laboratories – a mysterious company that has been advertising heavily on local television.

Richard meets Dr. Lock (DAVID WARNER) and his sexy blonde assistant (DEBORAH HARRY) and learns that he is a candidate for a rapid hair-growth solution. The process involves no surgery, no hair-weaving and no strange elixir. Richard is guaranteed to wake up with a full head of hair.

The next day, miraculously, he wakes up with more hair than he has had in years. He is jubilant. Megan cannot keep her hands off him. But Richard isn’t feeling well. He has a tickle in his throat. His hair continues to grow, and soon, it is down to his shoulders. As a hair stylist trims the hair, the cut strands have a life of their own as they scurry into the dark recesses of the floor. Richard is also unable to alleviate the tickle in his throat. Returning home, he discovers to his horror that hair is growing out of his throat. It is no ordinary hair. It has eyes and tiny sharp teeth.

When Richard returns to the laboratory, Dr. Lock is positively gleeful. Richard has unknowingly become the host for the vanguard of an invasion from outer space. Preying on the vanity of all Americans, the hair creatures begin to spread themselves out from the balding pates of men all across the country. It’s enough to make your hair stand on end… if you have any left following this story.

Brent Matthews (MARK HAMILL) is a major-league baseball prospect on a hot streak. He has a terrific future on the diamond and a wife named Cathy (TWIGGY) who is about to announce that she is pregnant. On the night that Cathy plans to spring her surprise, Brent’s world comes undone.

Driving home, he swerves to avoid a deer on the road and smashes into a telephone pole. Brent loses his right eye in the crash. While Cathy consoles him, two doctors hover nearby. Dr. Lang (JOHN AGAR) has spent the last ten years developing a method for eye transplant surgery. He wants Brent to be his guinea pig. Dr. Bregman (ROGER CORMAN), Brent’s family doctor, is skeptical. Wanting desperately to play baseball again, Brent gives his consent for the operation.

Lang succeeds in giving Brent a new eye. It’s brown, which hardly matches Brent’s other blue eye. But Lang says that a blue contact lens is being prepared which will ease the physical transition.

But the transition is anything but easy. Brent suffers from headaches, strange desires to dig in the family garden and frightening hallucinations, including images of bloody, mangled corpses, either sticking out of the backyard or appearing suddenly in the garbage disposal. Needles to say, his relationship with his wife darkens.

Brent’s sexuality begins to intermix with his visions as he begins to envision dead female bodies in the backyard. Brent contacts Dr. Lang and demands to know exactly whose eye he has been given. Lang admits that Brent has the eye of John Randle, a fiendish serial killer who was executed in the gas chamber. Brent then finds a micro-filmed newspaper clipping and learns the details behind the killer’s reign of terror – all of which corresponds to Brent’s frightening hallucinations.

Returning home, Brent has now virtually been transformed into Randle. He starts to dig what he refers to as "Cathy’s Grave" in the backyard. Between Brent’s own self-realization and Cathy’s professed love, he fights back against the hallucinations.

Back at the County Morgue, The Coroner is now the victim. Two men perform an autopsy on him. When they take a break, the Coroner, with innards oozing out of him, winks at the camera. "By the way, come by again some night," he says with a sly grin. "There are bound to be a few more good stories down here."
