Charles Bronson at 63 or so, continues his vigilante persona in this run-of-the-mill crime drama about a Richard Speck-style killer who knifes young nurses to death. There is no doubt that the film exploits both the heinous, 1966 Speck murder of eight nurses in Chicago and an audience's willingness to go along with the Bronson character, Leo Kessler, when he uses illegal means to entrap criminals. The captured killer, Warren Stacey (Gene Davis) manages to go free because of red tape and the need to wait for the outcome of his insanity plea. When he returns to his murderous predilection, Kessler takes action to permanently stop him. ~ Eleanor Mannikka, All Movie Guide
