Henry Morrison washes off blood in a bathroom, before changing his appearance and putting his belongings into a suitcase. After packing his things, Henry leaves through the front door of his house, nonchalantly passing the butchered remains of his family and others. Boarding a ferry, Henry throws the suitcase containing the objects from his former life into the ocean. One year later, Henry—now operating as a real estate agent named Jerry Blake in the suburbs of Seattle—has married the widow Susan Maine. Jerry's relationship with Susan's 16-year-old daughter, Stephanie, is strained. Her psychiatrist, Dr. Bondurant, advises her to give Jerry a chance.
