Plot summary
Template:Spoiler Norman Bates (Perkins) is still running his little motel, and he has his mother. One of his guests is Maureen Coyle (Scarwid), a young, mentally unstable nun who has left the convent where she lived after she murdered a nun who attempted to stop her from committing suicide. To get some help, he enlists Duanne Duke (Fahey), a young musician. One day Tracy Vennable (Maxwell), a nosey journalist, comes to seek him and ask questions about his past.
Those questions and some not so colorful characters lead to another knife wielding murder spree. But is the killer Norman or someone else...?
Norman is back up to his old tricks again by donning the wig and dress and killing women who he feels Mother is jealous of.
