Night of Deviant Sex (1983) Jess Franco

Moira - a beautiful and erotic cabaret dancer - is hired to impersonate another woman who turns out to be a secret agent and must receive an important message in Las Palmas de Gran Canaria. In that message is reported and discovered the hidden whereabouts of a very important character from World War II [a Nazi officer named Von Klaus] who once absconded with a vast fortune in gold. Aided by private detective Al Crosby, with whom her relationship goes beyond the limits of pleasure, Moira manages to locate the mysterious character." Based on the novel by David Khunne, don't you know.

Of course, Moira is portrayed by Lina Romay - who it must be said looks spectacular here - and the cast also features Eva Palmer (billed in other Franco movies as Lorna Green), Albino Graziani, Mayans' wife Juana de la Morena (whose vagina is cauterized by a hot curling iron), Tony Skios and Franco himself in a funny bit part.
