Professor John Vincent is on a biological research expedition in the Darien Gap, the most dangerous place in the Western Hemisphere. The impenetrable jungle on the border of Colombia and Panama was once the haunt of drug dealers and guerrillas, but it has been quiet in recent years.

No one suspects the forces converging on them. While a Colombian revolutionary group is about to restart the drug war, a renegade scientist has established his base in the jungle. Shadowy agents from the French government are also in the area.

Hunting them all are hungry creatures brewed in the mad depths of a genetic lab.

Will anyone survive the Jungle Lab Terror?
