A movie which shows the dismal social plague of the Mafia: a man imprisoned who comes back to his city and discovers that death of his wife was not an accident, an inquiry which goes on to catch "big fishes", honour questions to solve... Very good starting, good pictures, good dialogues too; nevertheless I don`t like so much this movie maybe because it deals with Mafia without posing you something new or something able to involve you. I think the title maybe was interesting in 1970, but today this subject has already been raised and I assert it`s an out-of-date movie. What is more, the entire subject is changed too: conditions, inquiries, the same Mafia: so the title remains like a documentary, and it`s no a value for a movie!
