Diana (Janine Reynaud) and Regina (Rosanna Yanni) are two wisecracking, super-sexy private investigators hired to find a missing doctor’s secret formula. In this way-out 1960’s spy-horror spoof from director Jess Franco. A sheet of music in a dead man’s hand is the girls’ only clue, and somehow it leads them to an island owned by a sinister man named Erik (Adrian Hoven).
Using a crazy nightclub act as cover, the restless vixens sing, dance and strip their way to the solution of the strange case, effortlessly eluding lots of drooling, knife-wielding psychopats along the way.
