In Psycho, Marilyn is a working girl in Phoenix, Arizona. She was tired of secretly dating Sam Looms during lunch break, because almost all the money he earned was used to pay alimony to his ex-wife and she couldn't marry her. One day, Marilyn's boss asked her to take 40,000 yuan in cash to the local bank. Because she wanted to change her life so badly, she fled the town on impulse and decided to go back to California with her lover Sam. When she drove away from the town, it got dark and it began to rain cats and dogs, so she had to drive off the highway. The fatigue of long-distance driving and the pressure of absconding with money almost made her nervous breakdown, so she decided to rest at the Bates motel on the roadside for one night. The owner of this motel is Norman Bates, an eccentric young man who loves and fears his mother who is ill in bed. No sooner had Marilyn finished the dinner Norman prepared for her than she went back to her room to take a bath. When she entered the bathtub and pulled up the shower curtain, a bizarre and horrible story was about to happen. In the past 40 years, Hitchcock's Psycho can be said to be the masterpiece of horror thriller. It was the most violent and erotic movie in Hollywood from 65438 to 0960. How many viewers are scared to take a bath alone by the pervert killer and the well-known bathroom killing scene in the film? The film was selected as one of the most important American films in 100 by American film institutions.
