This cheap little indie touches the semi-documentary bases at a time when Hollywood was boosting the image of federal agencies in general. After all, the Cold War was heating up; at the same time organized crime was growing, so who better than the FBI, DEA, Treasury Men, et al. as heroes for a new kind of documentary style. Many classics emerged from this period: T-Men (1947), Naked City (1948), Border Incident (1949). The better ones blended elements of noir with documentary naturalism to produce unusual effects.
This 1950 production echoes many clichés of the period (murdered agent, cutting edge technology, a Mr. Big et al.). But it's clearly a shoestring affair despite good intentions. At the same time, the lighting looks more like unpaid utility bill than nourish light and shadow. Nonetheless, the parking lot location shots provide good glimpse of Detroit's assembly line product, circa 1950. The screenplay manages some tension, but that final shootout looks poorly staged, as if no one fears getting hit. Strictly a low-grade effort at cashing in on a popular trend.
