Burlesque theater "Salon Rouge" star and co-owner Eva Baal has a fatal cardiac arrest during the new show's dress rehearsal, induced by heroin mixed into her 'regular' cocaine. Managing equal co-owner Dora Krumme, whom the team falsely suspected of murdering her partner in a defunct circus, sees no suspect. Bank officer and regular guest Raul Hübner was suspiciously generous with dubious credit, having a crush, and his wife Sonja took the theater's recent recruit Anna Thoman's burlesque dance course to re-boost their marriage. Eva's drug dealer presumably also supplied the heroin, but is found murdered himself. The eager beaver female uniformed officer volunteers the take the course undercover, which proves as dangerous as interesting, delving into Eva's extracurricular activities.
