The first movie filmed by the original Fabuous Five. The movie is a parody of classic murder mysteries, with exaggerated character tropes and cliches.
Rookie detective Athena Case is on the case when called to the scene of what appears to be domestic murder. Anna Smith was found slain in her bedroom. Possibe suspects include her hysterical overbearing mother, repressed older sister, and paranoid grandma that was unaware of her existence in the first place. Can Athena catch the perp before more bodies pile up? No. She can't.
