Psycho
In 1960 Alfred Hitchcock was already famous as the screen’s master of suspense (and perhaps the best-known film director in the world) when he released psycho and forever changed the shape and tone of the screen thriller.
In the opening scene an unmarried couple balances pleasure and guilt in a lunchtime liaison in a cheap hotel hardly a common moment in a major studio film in 1960. Marion crane (Janet Leigh) is unhappy in her job at a phoenix, Arizona real real-estate office and frustrated in her romance with hardware store manager Sam Loomis (john Gavin). One afternoon, Marion is given 40,000 in cash to be deposited in the bank. Minutes later, impulse as taken over and Marion decides to steal the money and takes off in her car, hoping to leave phoenix for good and start a new life in California with her lover Sam.
On the way to Sam’s California home, she parks along the road to sleep. A highway patrol officer awakens her and, suspicious of her agitated state, he begins to follow her. When she trades her car for another one at a dealership, he notes the new vehicle’s details,  by the time Marion returns to the road, there is a heavy rainstorm which prompts her to spend the night at the bates motel, where nervous but personable innkeeper normal bates (Anthony_perkins) cheerfully mentions that she’s the first guest in weeks. He tells Marion’s he rarely has customers has customers because of the new highway nearby, and mentions he lives with his mother in the house overlooking the motel. He then shyly invites Marion to have supper with him. She overhears Norman arguing with his mother about his supposed sexual interest in Marion, and during the meal Marion angers him by suggesting he institutionalize his mother. He admits he would like to do so, but does not want to abandon her.
Marion resolves to return to phoenix to return the money. As she undresses in her room, Norman watches through a peephole in his office wall. After calculating how she can repay the money she has spent. Marion flushes her notes down the toilet and begins to shower. Suddenly, an anonymous figure, presumably, Norman’s mother, enters the bathroom and stabs Marion to death. Norman finds the corps, and immediately assumes that is his mother committed the murder. He cleans the bathroom and places Marion’s body, wrapped in the shower curtain and all her possessions – including the money – in the trunk of her car and sinks it in a swamp
