Shriek If You Know What I Did Last Friday the 13th is a 2000 horror movie that parodies teen horror flicks like "Friday the 13th," "Halloween" and "Nightmare on Elm Street." The plot surrounds a group of students at Bulimia Falls High School who are getting picked off one by one. New kid Dawson Deary (Harley Cross) meets a new set of friends, Boner (Danny Strong), Barbara (Julie Benz) and Slab (Simon Rex), who are receiving notes from the killer stating "I know what you did last summer." A series of flashbacks reveals an incident that took place the previous summer involving several students. Sexy reporter Hagitha Utslay (Tiffany-Amber Thiessen) writes a book that points the finger at the person she believes to be the killer while security guard Doughy (Tom Arnold) launches his own investigation. The bumbling duo eventually joins forces to see if they can unearth the killer's true identity.
