About More Than Sisters
A young woman has been experiencing terrifying nightmares set in an asylum. Her husband, powerless to help her, enlists the aid of a detective to investigate her past, hoping for a clue to her present visions, but what he uncovers is more shocking than anyone could imagine.
Directed by Shaun Costello, More Than Sisters leans on a strong ensemble — Lynn Stevens, Jamie Gillis, Heather Young — to carry a story that balances spectacle with character.
The film landed with audiences for its craft and performances, and remains one of the most talked-about mystery titles of 1979.
