Suspecting that Buck Thomas (Michael Morrison, TABOO) - the owner of the Circle S swingers ranch - is plotting to kill his wife Cora (Lisa De Leeuw, BLOW-OFF!) for insurance money, private detective Nick (Paul Thomas, EMANUELLE AROUND THE WORLD) recruits virginal love interest Barbara (Anna Ventura, THE DEVIL IN MISS JONES PART II) to pose as his wife at a swingers weekend to do some investigating. Also joining them for the weekend are more experienced swingers Francine (Sharon Kane, PUSS 'N BOOTS) and Jack (Ken Starbuck, SEXCALIBUR), their newbie guests Laura (SAME TIME EVERY YEAR's Tiffany Clark, who also performed the title song and served as assistant director) and Frank (Michael Bruce, BABYLON BLUE), and a masturbating pervert (Joey Silvera, THE FIRST TIME) among others. When things heat up, Nick warns Barbara to leave but ends up deflowering her. Their ensuing continuing bedroom antics as well as Barbara's jealousy over Nick's probing interrogation tactics leave little time for investigation but plenty of time for the audience to witness the various couplings up to and including the ranch's Friday night bash (which includes a choreographed hardcore ballet number). By that point, Nick or Barbara no longer care about the murder plot and neither does the audience (which is just as well as the film drops it in favor of more sex scenes until it reaches the required running time).
