Undercover cops -- and foster brothers -- John (Wesley Snipes) and Charlie (Woody Harrelson) work the Big Apple's subway system sniffing out criminals. But compulsive gambler Charlie decides to become a lawbreaker himself when he gets in hock to the mob to the tune of $15,000. Setting his sights on the "money train" -- the one carrying the day's transit fares -- Charlie hatches a heist. It's up to John to scotch the plan … or help execute it.
