Prolific Italian exploitation filmmaker Sergio Martino (Torso) directed this erotic <i>giallo</i> thriller in Argentina. Debora Caprioglio, the fourth wife of Klaus Kinski and co-star of his flamboyant career-ending epic Paganini as well as the cult favorite Paprika, stars as Marina, the frequently nude temptress who seduces and eventually destroys the film's protagonist, an assassin named Mark Derrick (Steve Bond). Derrick, a disgraced Miami police officer who was fired and turned snitch to avoid prison on charges that he was on the take, arrives in Buenos Aires after being hired to kill a gang leader. He gets an apartment to wait for the final order and hears sounds from next door of a woman crying, singing, and having passionate sex. Mark begins spying on the woman, Marina, and her abusive boyfriend, and it isn't long before Mark and Marina are having an affair of their own. Naturally, the next step is eliminating the boyfriend, and it turns out that he was Mark's target all along, but things get a great deal more complicated before this voyeuristic thriller winds to a close. Sharon Twomey co-stars with Leonardo Treviglio and Raffaella Offidani.
