Plot summary

'Prologue'A creepy-looking coroner (John Carpenter) introduces three different horror tales involving his current work which are cadavers in "body bags".'The Gas Station'Anne (Alex Datcher) is a young college student who arrives for her first job at working the night shift at an all-night filling station. The attending worker, Bill (Robert Carradine), leaves and tells her that a serial killer has broken out of a mental hospital and cautions Anne to be careful and not leave the booth at the station which is to be kept locked at all times. After Bill leaves, Anne is alone as the tension mounts as she deals with various late-night customers seeking to buy gas for a quick fill-up, while Anne remains locked in her booth, unsure of who may be the escaped maniac. Eventually, when Anne suspects that the escaped killer is lurking around the gas station, she tries to call the police, only to find the phone line dead. Soon after, she finds a dead body in one of the lockers, which is a station attendant who has a nametag saying 'Bill'. Anne realizes that 'Bill', the attending worker whom she interacted with earlier, is in fact the escaped killer whom has killed the real Bill and has taken his name and uniform, and is killing numerous passersby. 'Bill' appears and attempts to kill Anne with an axe by breaking into the locked booth, and then chasing her around the deserted garage. Just when he is about to kill her, one customer returns after forgetting his credit card. Together, they stop the killer by throwing him under a car on a garage rack in which Anne pushes the lift button making the car come crashing down, cutting the deranged killer in two.'Hair'Richard Coberts (Stacy Keach Jr.) is a middle-aged businessman who is very self conscious about losing his thinning hair. His obsession about going bald and his means to keep his pride and self esteem intact has caused a riff between him and his long-suffering girlfriend Megan (Sheena Easton). When Richard answers a television ad about a 'miracle' hair transplant operation, he pays a visit to the office and meets the shady Dr. Lock (David Warner) whom, for a very large fee, agrees to give Richard a scalp treatment to make him grow his back hair. The next day, Richard wakes up and removes the bandage around his head left after the surgical procedure and is overjoyed that he has a stallion-style full set of hair. But over the next few days, Richard becomes increasingly sick and fatigued, and soon he finds himself growing hair on parts of his body (the palms of his hands, etc.) that do not grow hair at all. After trying to cut some off, he finds that his hair 'bleeds', and after examining it under a magnifying glass, sees that they are alive. Richard goes back to Dr. Lock for an explanation, but finds himself a prisoner as Dr. Lock explains that he and his entire staff are aliens from another planet who seek out narcissist humans and plant their seeds of hair to grow and takeover their bodies for consumption as part of their plan to spread their alien essence to the planet. Richard was just their latest victim.'Eye'Brent Matthews (Mark Hamill) is a Major League Baseball player who's life and career takes a turn for the worse when he gets into a serious car accident in which his left eye is gouged out. Unwilling to admit that his career is over, he jumps at the chance when a doctor tells him about a experimental surgical procedure to replace his eye with one from a recently deceased person which can restore his sight. After the surgery, Brent can see through his new eye and is overjoyed at this miracle. But soon after, Brent begins to see things out of his new eye that others cannot see, and it puts him and his wife, Cathy (Twiggy), in danger as Brent begins having nightmares of killing women and having sex with them. Brent seeks out the doctor who tells him that the donor of his new eye was a recently executed serial killer and necrophile who killed several young women, and then had sex with their dead bodies. Brent becomes convinced that the spirit of the dead killer is slowly taking over his body through his eye and enabling him to resume killing women. After Brent blacks out and wakes up near a crime scene where another young woman is killed, he flees back to his house where he tells the skeptic Cathy about what is going on with him. Just then the spirit of the killer emerges and attempts to kill Cathy as well. Cathy fights back, subduing him long enough for Brent to re-emerge. Realizing that it will only be a matter of time before the killer reemerges again, Brent cuts out his donated eye, severing his link with the killer, but he dies afterwords due to bleeding to death.'Epilogue'The Coroner finishing telling his three tales to the viewers when he hears a noise outside the morgue and crawls back inside a body bag revealing that he himself is a living cadaver this entire time, as two other morgue workers begin to go to work on this 'John Doe' corpse that was just delivered to them.
