Something's happening in the underworld of Cook County. Tensions are rising between two rival drug lords, and the streets are their battleground. Sergeant Frank Leal and his former partner, Olivia "Ollie" Hart, get involved when one of their informants turns up dead with his ear cut off. When one drug lord decides it's time to eliminate the competition completely, the takeover becomes very hostile indeed. As blood flows in the gutter and retaliation rules the day, Leal and Hart have to stop two criminal armies before they meet in an all-out war with the innocents caught in between.
