Richard Coberts is a middle-aged businessman who is very self-conscious about his thinning hair. This obsession has caused a rift between him and his long-suffering girlfriend Megan. Richard answers a television ad about a "miracle" hair transplant procedure, pays a visit to the office, and meets the shady Dr. Lock, who agrees to give Richard a solution to make his hair grow back. The next day, Richard wakes up and removes the bandage around his head, and is overjoyed to find that he has a full head of hair. But soon he becomes increasingly sick and fatigued, and finds his hair continuing to grow and, additionally, growing out of parts of his body, where hair does not normally grow. Trying to cut a hair off his mouth, he finds that it "screams", and, examining it under a magnifying glass, sees that it's alive and resembles a tiny serpent. He 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, seeking out narcissistic human beings and planting seeds of "hair" to take over their bodies for consumption as part of their plan to spread their essence to Earth. Soon after this reveal, according to the coroner, he jumps off of the building on top of a moving car and then dragged by a moving train. Brent Matthews is a baseball player whose life and career take a turn for the worse when he gets into a serious car accident in which his right eye is gouged out. Unwilling to admit that his career is over, he jumps at the chance to undergo an experimental surgical procedure to replace his eye with one from a recently deceased person. But soon after the surgery he begins to see things out of his new eye that others cannot see, and begins having nightmares of killing women and having sex with them. Brent seeks out the doctor who operated on him, and the doctor 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 taking over his body so that he can resume killing women. He flees back to his house and tells his skeptical wife, Cathy, about what is happening.
