This film is a precursor to "Serpico" starring Al Pacino many years later. It's the story of an honest cop surrounded by corrupt and cowardly police officials who are in the take of a powerful city mafia. It's like Chicago during the times of Al Capone. The script is well written and has a good pace. The scenes are neither too short or too prolonged, just the right amount to move the story along. The actors played their parts well: Lee Marvin as a sadistic degenerate thug is very convincing as is Gloria Grahame playing his not so empty headed girlfriend, who has more depth and humanity than meets the eye. Jocelyn Brando (Marlon Brando's sister) played a small but very convincing role as Detective Bannion's loving and supporting wife, who encourages him to be the honest cop that he is. Their best scene together is right before she gets blown off in the car. It's a very tender, sentimental family scene when their daughter interrupts their kissing because she cannot go to bed. This is actually the pivotal scene of the film because Katie's violent death becomes Bannion's main motive in getting her killers. Jocelyn Brando plays the role of the perfect woman: dedicated wife, mother and the moral support behind her husband and Glenn Ford plays the role defending this order of things. In the end, he triumphs over those who seek to destroy this order: Lee Marvin and his thugs. The film makes a strong case for this theory with the hope that the natural order of things has been restored.
