A violent robber is loose in River City. Meet the cops that must take him down. Stefan Kopriva, a young hotshot. Katie MacLeod, a woman in what is still mostly a man's world. Karl Winter, about to retire but with one more good bust left in him. And Thomas Chisolm, a former Green Beret who knows how dangerous a man like the Scarface Robber can be. These are the patrol officers of River City—that mythical thin blue line between society and anarchy. They must stop the robber, all the while juggling divorces, love affairs, internal politics, a hostile media, vengeful gang members and a civilian population that isn't always understanding or even grateful.
