Lois: I didn’t know what I was doing! You know the truth!
Ed: The truth can get you twenty years!
In San Francisco, Lois Frazer (Jane Wyatt AKA Spock’s mom in Star Trek), is set to divorce her fortune-hunter husband, Howard. Once he leaves for the airport, she finds out that he bought a gun, and thinks he plans to kill her. Lois frantically calls her lover, who happens to be an experienced homicide detective, Lt. Ed Cullen (Lee J. Cobb). Ed arrives at her house to calm Lois down. Soon after, Howard unexpectedly returns, and she shoots him dead! Ed (though he knows better) feels compelled to cover up the killing. Soon, he’s assigned to investigate the case. His younger brother/new detective, Andy (John Dall), is also assigned and anxious to prove his merit. Andy is getting married in a few days.
Ed: [to Andy] Better learn one thing: never take a case to bed.
We see locations in and around the Golden Gate Bridge, Fisherman’s Wharf, Telegraph Hill and Fort Point (which was used in Hitchcock’s Vertigo). There are some colorful supporting characters who add to the drama. The action (incl. car chase) scenes are done well. TCM’s Eddie Muller explained that this film was made on a small budget and produced by Jack M. Warner, who was fighting w/ his father, the Jack Warner. The son wanted to make films on his own. The director, Felix Feist, was a freelancer (not tied to any studio); he was married to Lisa Howard (who plays Janet- Andy’s wife).
Unlike Dall, Howard’s performance is natural and easy. Andy needed more characterization; he comes off as too dreamy-eyed for a cop. You also have to ignore the fact that Dall (tall/blonde/slim) and Cobb (short/dark-haired/stocky) look and sound nothing alike! It’s rare to see Cobb as a leading man; he tones down the brooding intensity and growling voice (which we know/love from his character roles). Sadly, Cobb and Wyatt (cast against type as the femme fatale) lack romantic chemistry. I did like their last scene together, which was enigmatic and had some smolder! Cobb got this role after a successful run on Broadway in Death of a Salesman. Arthur Miller wrote the role of Willy Loman w/ Cobb in mind -WOW!
 …it is relentless and edgy, with no time for polish or emotional depth. Cameraman Russell Harlan (Blackboard Jungle; To Kill a Mockingbird) does a brilliant job with great angles and framing. It isn’t elegant, but it’s visually sharp.
 A fast, curious, edgy crime film that depends on a fabulous, simple twist, which you learn right at the start and keeps you on the edge of your seat the whole time. The clash of two cops who are brothers begins innocently, and turns and builds in a very believable way…
Lee J. Cobb… just perfect in his role, right to the last scene when you see him look down the hall with the same feeling he has at the beginning of the film.
