Downtown - Die nackten Puppen der Unterwelt (1975)

A private eye who's over his head in debt takes on a job snapping photos of his client's rich husband in bed with another woman. But when the husband winds up with three bullet holes that seem to have come from the private eye's own gun, he's got to prove he's not the murderer meanwhile getting tangled deeper in a web of deceit, lies, and steamy night club dancers!
