When Drake's first team of well-armed mercenaries gets wiped out within hours of setting down in the jungle, he turns to one lone hunter, The Cajun, to go in single-handedly. But will The Cajun be cunning enough to find the creatures and destroy them before they turn the blue waters red with the blood of tourists.
