Virginia Mayo portrays a questionable individual in this film, and her performance is surprisingly good given how infrequently she takes on such roles as the deceptive central figure. She’s romantically involved with "Colby," portrayed by Zachary Scott, who happens to be a lawyer—a fundamentally honest one, though frequently beholden to the corrupt "Hap" (Douglas Kennedy). When a member of Hap's group meets an untimely end, “Flaky” appears likely to face the consequences; however, her boyfriend believes he possesses the legal acumen to exonerate himself and willingly accepts responsibility. It isn’t until his trial begins that these former allies shift their position, effectively condemning him to two decades in prison. Displeased with this outcome, he manages to evade his security detail on a train, narrowly avoiding being hit by "Nora" (Dorothy Malone), who tends to his injuries and becomes convinced of his narrative regarding wrongful accusation and the pursuit of justice. Now, he must return to the city and, equipped with additional details, rectify the situation. Mayo appears at the beginning and conclusion, while Malone occupies a more central role throughout much of the movie's duration. Elisha Cook Jr. delivers a noteworthy performance as the violent enforcer "Roper," and Scott, combined with some moody lighting and a reasonably brisk narrative, contribute to maintaining viewer interest until a suitably appropriate—though somewhat convenient—resolution.
