While on vacation in New Orleans, Jack Slade is approached by a young
woman whose family holds a dark secret. She asks Slade to prevent her
cousin, a powerful vampire, from succeeding in his bid to take control
of the world. Slade takes the job and follows a trail of blood that
leads him into the dark world of Voodoo where he battles murderous
zombies and the vampire's henchmen. In the brooding, snake and alligator
infested swamp around Lake Pontchartrain, Slade has his final
confrontation with the vampire himself in a fight to the death.
