what is psycho about

Psycho is a 1960 American suspense and psychological thriller film directed by Alfred Hitchcock, based loosely on the real-life crimes of Wisconsin serial murderer Ed Gein. The story centers on Marion Crane, a secretary who steals $40,000 and takes refuge at the eerie Bates Motel, run by the shy and awkward Norman Bates and his domineering mother. Marion is fatally stabbed while taking a shower, and the mystery of her disappearance unfolds as her boyfriend and sister investigate. It turns out Norman Bates suffers from a split personality disorder that leads to murder, with his "mother" actually being an alternate personality of Norman himself. The film is famous for its iconic shower scene, suspenseful atmosphere, haunting score, and its influential role in the horror genre, particularly as an early example of the slasher film.
