However, Alec suspects that one of his gang is betraying him and he then gets a phone call which confirms things to him....
This is a boys film about gangsters. The only woman with any kind of role - Judy (Barbara Lawrence) appears briefly and gets slapped about - I'm not sure her role has any relevance. The story is good and both the main characters, Mark Stevens and Richard Widmark, play their roles convincingly. A slight irritation is the narrator at the beginning - I wished he would just shut up and let the film take its course. Similarly, there are a few overlong sequences of police checking but overall it's a good film. However, it would have all ended differently were it not for an unsung hero, a cab driver (Charles Tannen).
