National Security is under siege again by foreign agents at work providing "dirty bombs" to terrorists - and they're assembling them right here under our noses. If their cunning plot succeeds a slow and painful death awaits millions in cities across the entire eastern seaboard. The frigid Alaska-Yukon Klondike is the locale for this action-packed drama where bad guys can cover their tracks with murder and get away with it - until Phil Bragg's NSA agents cross tracks with them. Intercepted calls and daring footwork expose this terrorist axis; and the enticing dance hall girls find out the way to go. But will it be in time to stop the assassins biking across the continent to kill the only ones who know where the bombs are placed - the ones who put them there? All the exciting NSA players are back in action with the FBI and their Angel as partners. Suspense is gripping, characters are engaging and romantic values are exalted as good vs. evil in this thriller - and it's safe for teens.
