The full film used to be up on Youtube, gone now.
Here's a full review from a horror site -
" Around New Orleans, Marie Ryan shows up looking for her missing twin sister Vicky. She enlists the aid of detective Jack Craig to find her. Unfortunately, Jack is made out to be an obnoxious dick in the dub, so it's impossible to care much as you follow him around the swamps looking for the missing girl. The two learn that Vicky had moved in with a strange woman named Olivia and disappeared soon after that. Olivia turns out to be a voodoo priestess with a bodybuilder-sized "zombie" sidekick (in no makeup) who runs some slave camp deep within "Voodoo Swamp." Marie and Jack hop in a canoe and decide to see if they can find her, and run across all kinds of horrors, such as deadly animals (rattlesnakes, a tarantula, a crocodile) that never cross into the frame with the actors, a skull on a stick and (gasp!) some guy standing in a field picking cotton, which requires a couple of long shots. It's every bit as exciting as it sounds.
The action, horror and excitement quotient is almost nil, and you'd be hard pressed to find a movie with this much filler. At the beginning there's a brief scene at a titty bar with two brief shots of a stripper wearing silver pasties. And there's a flashback where some woman at a party unenthusiastically dances for a couple of minutes next to a table with two candles and some beer bottles. And there's an underwater wrestling match between Jack and the zombie bodybuilder that ends in Jack - still alive - being picked up and hurtled toward the shore. Marie (who looks an awful lot like BLOOD OF THE ZOMBIE star Linda Ormond, and might actually be her) gets wet and has to change clothes, so there's one muddy shot of her in her bra and one from behind as she puts on a new bra (nope, no nudity... hey, this is 1960 something). The last couple of minutes finds time for a decapitation and our "hero" crashing a voodoo ceremony with a machine gun, but it's too little, too late and too badly done. And despite the constant incompetence, there are just a few choice bad movie cheap laughs; my favorites being the dubbed over kid's voice (obviously an adult imitating a child) and during the climactic voodoo ceremony when they apparently couldn't find a drum so they just had one of the black extras beat against the side of a boat.
In short, this is certainly some kind of discovery. How many unreleased, unheard of regional horror films from the 1960s do you see cropping up on DVD these days? Still, it's very easy to see why this never really saw the light of the day until 40 years later. It's ineptly made, obviously no one even bothered to finish it and worse of all, it's incredibly boring from start to finish. "
