Marion Crane steals $400,000 from her employer to get her boyfriend, Sam Loomis, out of debt. She flees Phoenix, Arizona, by car. While en route to Sam's California home, she parks along the road to sleep. A highway patrol officer awakens her and, suspicious of her agitated state, begins to follow her. When she trades her car for another one at a dealership, he notes the new vehicle's details. Marion returns to the road but, rather than drive in a heavy storm, decides to spend the night at the Bates Motel.
