Andrea Artusi (Ugo Tognazzi) begins to have doubts about the loyalty of his beautiful wife, Maria Grazia (Claudia Cardinale). When doubt becomes an obsession, his behavior becomes completely crazy, stalking her relentlessly. Another great success of the Italian director Antonio Pietrangeli, also starring Bernard Blier, Salvo Randone and a cameo from Gian Maria Volonté.
