Handsome, smooth Ray Danton ("The Rise and Fall of Legs Diamond") stars as Johnny Salvo, ex-con turned serviceman who's recruited by Uncle Sam to participate in an operation designed to bust murderous counterfeiters. His specific job involves getting to know the widow (Leigh Snowden, "The Creature Walks Among Us") of an Army acquaintance who was gunned down in Europe, and who had been involved with the counterfeiting ring.
For Johnny, this is not an ideal situation because he has to work with his own father (Onslow Stevens, "Them!"), a Federal agent whom he feels wasn't there for him when he needed him most. Of course, he still resents the old man.
The story, written by Danny Arnold, is not a great one; the film overall is pretty routine, playing out with no real surprises. But it still serves its purpose as a crime drama programmer, and *does* entertain, with a first-rate director in Jack Arnold and a very good cast that plays their parts to perfection. Lots of familiar faces appear, with good-looking Grant Williams playing a real heel a year before Arnolds' "The Incredible Shrinking Man" boosted him to star status.
Danton is fine in the lead role, having decent chemistry with pretty leading lady Snowden. Williams is fun playing the jerk / bad guy determined to claim Maria for himself. And Stevens is great as the father who's just as determined to make it up to his son; he and Danton have some of the best scenes in the film.
Definitely a must-see if you're a Jack Arnold completist.
Six out of 10.
