An excellent opening title sequence starts this gritty Noir off in perfect step with what will follow. The son of a thief who was killed while attempting to shoot himself out of jail, Mark Dixon became a cop in an attempt to atone for the sins of the father, but cannot quite escape the fathers blood surging through his veins every time he strikes out at a hood, and it's his excessive use of force that gets him demoted with the threat of losing his job as detective, the only thing he ever wanted out of life. When he accidentally kills a witness to a murder, panic takes hold of him and he proceeds to cover up the evidence, but fate has a way of meting out cruel justice. Mark will fall in love for his victim's ex, and then her innocent uncle through another freak accident ends up taking the rap for the murder when the body turns up. And now the real moment of truth - atone for his own sins and free an innocent man, but probably lose the girl, or say nothing, keep the girl, but end up being just like his father? A brilliantly executed noir by Preminger and Dana Andrews nails one of the best performances of his career as the tormented detective.
