Quick Answer

What is Psycho Sisters about?

Psycho Sisters is a 1974 American horror film directed by Reginald Le Borg about a grieving woman consoled by her younger sister, whose motives soon come under suspicion.

Programmer's Pick

Reginald Le Borg serves up a slow-burn family horror where sisterly love quickly curdles into something far stickier. With Susan Strasberg and Faith Domergue circling each other, this is a study in domestic dread that keeps the knives (and suspicion) sharp.
