Ten years earlier this programmer would likely have been a noir. As is, it's a pretty good little crime drama. Detective Harper is a violence prone cop, probably why he doesn't get promoted. And being a cop appears his whole life; that is, until he meets spider woman Holly who's connected to a jewel heist that Harper's investigating. Well, one thing leads to another, and soon he's caring more about her than solving the crime. Still, he's a sharp cookie in covering his tracks, especially now that he's got Holly and a bead on the jewels, and maybe a new carefree life away from an unappreciative detective bureau.
The principals do pretty well in their roles, while I couldn't help noticing a resemblance between actor Foster and the better known Tony Curtis. The screenplay does a pretty good job tracking Harper's absorption into the cage of evil. However, veteran budget director Cahn adds little to the filming. One story change I think would have deepened things is that of giving Harper a home life, maybe a wife. That way his down-spiral would have had a tragic dimension as well as being an unfortunate tale of woe.
Anyway, the flick's better than I expected without being anything special.
