The synopsis: The shy, awkward owner of a motel, Norman Bates (Anthony Perkins), tries covering up a series of murders (including Janet Leigh's famous death-by-butcher-knife while showering) perpetrated by his insane mother.
The twist: Norman has a split personality (one is him, one is his long-dead mother), and he's actually been killing everyone himself while dressed up as his mum. Scary bonus? He has her skeleton sitting in a rocking chair in his basement. You could almost call him a . . . PSYCHO. Ha! Ha! Ha!
The amount of damage it'll do to your psyche: 🔪🔪🔪🔪🔪
