Sergio Martino directs this 'giallo' thriller based on the short story 'The Black Cat' by Edgar Allan Poe. Luigi Pistilli stars as Oliviero, a failed writer and alcoholic who is abusive to his wife Irina (Anita Strindberg). Irina finds herself irrationally terrified of Oliviero's cat, Satan. When Oliviero's mistress is found dead he is in the spotlight, so on discovering the murdered body of the maid at his home, Oliviero chooses to hide it believing he would almost certainly be charged with both murders. With the killer still at large, Oliviero receives an untimely visit from his niece Floriana (Edwige Fenech) who manipulates both him and Irina, adding to the atmosphere of stifling paranoia and fear.
