Filmed in the split-screen wonder of "Duo-Vision"─showing different stories (or the same one, from different angles) simultaneously─this campy, creepy thriller follows a psycho killer preying on beautiful blondes staying at a California beach resort. Will her donning of a blonde wig make the singer ex-wife of the hotel detective the madman's next victim? David Bailey, Tiffany Bolling, Edd "Kookie" Byrnes, Diane McBain, and Randolph Roberts star. 95 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital stereo.
