When the sniper-style murder of an alligator poacher puts two rival families on edge, Police Sniper London Carter and Detective Sergeant Dawn Luke join forces to solve the case. But they'll have their work cut out for them as the two families recruit small armies to fight each other.

It doesn't take London long to realize they're dealing with a professional killer, but the motive for the murder is far from clear. Will he and Dawn solve the case before it's too late, or will the swamps of Louisiana run red with the blood of the rival families and the cops who are trying to stop them?
