This 1978 thriller stars Dianne Hull, Bo Hopkins, Sharon Farrell and Robert Englund based on true events. This tells about a disco dancer, Kelly (Hull)
who decides to drink one night to get over a failed relationship, but is drugged. Soon, she's committed to a psychiatric hospital because she's thought to be suicidal and is confined to the fifth floor where she befriends a group of seemingly, unbalanced patients. Kelly finds herself in
a nightmare trying to prove that she's sane, but it becomes impossible and
she endures the floor's negative aspects like Carl (Hopkins), a sexual predator, orderly. Farrell plays Melanie, a very depressed, patient Kelly befriends and Englund (A Nightmare on Elm Street) plays character acting, patient, Benny. This isn't a bad thriller featuring a decent cast, especially the attractive, Hull and tense moments. Give this one a view if you're into psychological thrillers.
