Richard Lemieuvre and Guy Royer (with moustache and bushy perm) are investigating a clinic in the country where the nurses provide very peculiar services to the (presumably sexually dysfunctional) male patients (Dominique Aveline and Jacques Gatteau). The investigators are found shortly after Cyril Val is admitted, but not in advance of they have discovered his address. They are chased into Paris by 2 of the nurses and try to hide in his apartment. There they discover Elisabeth Buré who welcomes em with open legs.
