An isolated firefight off the Gulf of Mexico disturbs Johnny Bolan enough to put in a call to big brother Mack. They discover mercenary collusion with local rebels on a tiny Caribbean island... and hints of Mob involvement in a run-of-the mill peasant rebellion.

A hard probe into a merc compound deep in the Louisiana bayou goes to hell after the first shot, leaving the Bolan brothers with little more than a new wild card in the deck: a lady Fed. The trio tracks the Mafia connection to its final resting place, courtesy of a few well-aimed kill shots, but the big picture remains out of focus. As the cold trail stateside leads to international waters, a virulent enemy is baiting a new hook.
