Alone in the Dark (1982) is a psychological horror–thriller that blends slasher elements with themes of madness and institutional failure. The story unfolds in a small coastal town where a violent power outage creates the perfect conditions for chaos. During the blackout, several dangerously unstable patients escape from a mental institution, each driven by deeply rooted psychoses and personal obsessions.

The narrative focuses on Dr. Dan Potter, a young psychiatrist who becomes the primary target of the escaped inmates, particularly one patient who harbors a personal vendetta against him. As darkness envelops the town, the boundaries between sanity and insanity collapse, forcing Potter and his family into a desperate struggle for survival.
Atmospheric and tense, Alone in the Dark distinguishes itself through its emphasis on character psychology rather than gore. The film explores fear born from the loss of control—both electrical and mental—making it a distinctive entry in early 1980s horror cinema.
