The Colonel and Ana Paulanos are captured by DCO when they sell Martin a briefcase of VX that turns out to be bogus. In response, one of The Colonel's followers releases real VX on a crowded bus, threatening more attacks if The Colonel and Ana aren't released. As a last resort, Martin stages a pulse-pounding "false flag" prison break of The Colonel and, with Ana's help, forces The Colonel to lead him to the VX . Can Martin trust Ana to betray The Colonel and help him find all the gas before more civilians are killed?
