With Jonathan Washington in the hands of the ATF, it looks like the gun-bust mission is nearly complete - until "The Bloody Pierce," a Russian hitwoman in a bulletproof coat, shows up and starts wiping out evidence. With a rumored mole in the ATF and good guys getting killed left and right, Bill and the Gunsmith Cats are forced to work underground. Working off of a tip they got from Washington, the Cats locate one of the gunrunners' arms storage facilities, but things take a turn for the worse when the guards spot them. Bloody Pierce captures Minnie May and Rally has to race in reckless pursuit to rescue her best friend from being carved up by the sinister Russian.
