When Detective Sam Tyler poses as a streetwise tough to infiltrate a vicious New York City gang suspected of truck hijackings, he's pushed to the limit not to blow his cover, and he reveals a much darker side. A bare-knuckled fist fight with a gang member, a late-night deal to buy a truckload of stolen VCRs, and even time behind bars at his own 125th Precinct are all necessary elements of Sam's scam. But can he keep up the ruse when he's told to shoot a bound-and-gagged woman? And his attraction to the gang leader's sister also seems to be part of a recipe for disaster.
