A murder occurs, and a witness tells the police that she will never forget the killer’s face. Mob attorney Walter Colby (Scott) is called by crime boss Hap Richie (Douglas Kennedy) in the middle of the night to arrange bail for his hood Caesar (Jack Overman). After doing so Colby tells his girlfriend, showgirl Flaxy Martin (Virginia Mayo), that he wants to quit the organization and become respectable. She pooh-poohs the idea, telling him that he does not have enough money to do so, or afford her.

She would know, as she is two-timing him with Hap.

Meanwhile, Hap arranges through Flaxy for a perjurer, Peggy Farrar (Helen Westcott), to testify on behalf of Caesar, clearing him of the crime. Afterward, she seeks to blackmail Hap for $10,000 to maintain her silence.

Outraged at the double cross, Flaxy loudly assails Peggy at her hotel apartment, drawing the attention of its desk clerk. Caesar silently shows up and kills her, leaving Flaxy later accused of the crime.

She goes to Colby for help, who comes up with a plan to clear her by confessing to be the murderer himself. With absolutely no evidence connecting him to the crime, he is confident of his acquittal. All goes well during the trial until an obvious perjurer takes the stand, again arranged by Hap, clearly with the acquiescence at the least of Flaxy. Colby is convicted on his testimony and sentenced to a hard time.

Before he is transferred to prison, he is visited by Sam Malko (Tom D'Andrea), a former client who feels he owes Colby a good turn. Sam tells him that Caesar has been getting drunk and bragging about how Colby was convicted instead of him. Colby’s suspicions towards Flaxy begin to grow.

En route to the 20 years awaiting him, Colby slugs his guard and jumps off a train in the countryside. Injured, he passes out in front of motorist Nora Carson (Malone), who takes him home and nurses him. She proves inexplicably attracted to him, in spite of his self centeredness and repeated lack of gratitude. A statewide manhunt seeks his every trace, which he and Nora elude.

He returns to the city and seeks Sam‘s help, leaving Nora behind as he arranges a rendezvous with Caesar. When he gets there he finds Caesar dead, and once again ends up at gunpoint with Caesar’s hood Roper. The two have a violent showdown on a rooftop, with Colby forcing his pursuer over the edge to his death.

He then heads for Flaxy’s apartment for a confrontation. When Hap arrives she pulls a gun on both men, seeking to disappear with $40,000 of Hap’s money and leave the pair of rivals hanging. Colby tells her she can’t shoot both men at once, and whomever she doesn’t will get her. Colby flicks off the lights and she shoots wildly at both, killing Hap. Colby calls the police, who come and arrest her.

Arriving back at Sam’s with the stolen $40,000 he insists he’s going to go on the lam with Nora. Nora does not want to go "on the lam" with him and says she is taking a bus back to her home. Sam counsels reason and tells Colby he is making a big mistake. Colby gives in and calls the police to pick Nora up at the bus station if they want to capture Colby. He meets her at the police station as he is turning himself in.
