The third installment in the “Nightmare on Elm Street” series. In a medical facility, seven teenagers who have constant nightmares about child murderer Freddy Krueger undergo monitoring for sleep disorders. But nothing that anyone does seems to help them — until Nancy Thompson, the heroine of the first movie, joins the medical staff. She suggests that they try a new drug, which inhibits dreaming, on the youngsters. The gullible doctor-in-charge opposes this treatment, forcing Nancy to fight both him and a suspicious nurse in order to save the teens. Meanwhile, Freddy gleefully unleashes one horror-filled image after another to traumatize the patients… Till they fear that this is one nightmare they’ll never wake up from again.
