About

You can watch Diabolique (1955) for free on Darkroom, or rent on Artify.

The cruel and abusive headmaster of a boarding school, Michel Delassalle, is murdered by an unlikely duo -- his meek wife and the mistress he brazenly flaunts. The women become increasingly unhinged by a series of odd occurrences after Delassalle's corpse mysteriously disappears.

Shadows stretch across a cold, opulent boarding school where suspicion curdles into genuine hysteria. This razor-sharp suspense ride turns a calculated murder plot into a claustrophobic nightmare of vanishing bodies and fractured sanity.
