Tango of Perversion (1973)

Athens, Greece, 1973. To satisfy his perverted needs, put-upon paraphiliac Ioakeim, an impotent trust fund baby rejected by women, likes to hole up in the secret room of his isolated villa. From there, Ioakeim can indulge his twisted passion for the forbidden: he captures on tape the bedroom antics of his frenemy Stathis, a macho ladies' man and sleazy coke-dealing gigolo using women to support his decadent lifestyle. But all good things must come to an end. And when the violent toy boy catches his coke-addicted girlfriend and a predatory bisexual in the act, Ioakeim discovers his true self--a dark side deriving pleasure from a newfound, grotesque sexual fetish.
