The Last Judgement But One(1979)

The relationship of István Kozár and his wife has reached the point where neither is prepared to hear even a single word from the other. The woman travels to the countryside because she needs a little time by herself. The next morning the police inform the man that his wife has died. István, who has fantasized on more than one occasion about strangling the woman, soon finds himself being investigated by detectives who expect a confession from him.
