Murder à la Mod  (1968)

Theatrical Release Information:
Murder à la Mod

A man is being blackmailed by his wife, who wants him to get out of the pornography business. His girlfriend steals some jewels from a friend to help the financially strapped man, but she ends up being a murder victim in his studio, and the man must track down the killer to clear his own name. The trail leads to three possible suspects, all with a motive for murder. Brian De Palma relies more on visual effect than character development in this independently produced film. ~ Dan Pavlides, All Movie Guide
