So Sweet... So Perverse

Jean Reynaud (Jean-Louis Trintignant) is a wealthy Paris industrialist whose marriage to Danielle (Erika Blanc) has gone slack, and his affair with the troubled Nicole Perrier (Carroll Baker) is the kind of risk he can afford. Nicole comes with an abusive boyfriend, Klaus (Horst Frank), and that is where Jean's money stops being any protection. Umberto Lenzi follows a man who took his comfort for granted and now watches it slip away.
