Set 22 years after the first film, it follows Norman Bates after he is released from the mental institution and returns to the house and Bates Motel to continue a normal life. However, his troubled past continues to haunt him as someone begins to murder the people around him. From the 1983 film Psycho II, this is Norman’s (Anthony Perkins) retractable knife used during stabbing scenes to appear as the knife blade is penetrating the victim. The knife blade has been made hollow with the tip being spring loaded making the tip stay out until the effect is needed.
