A brother, sister, and her boyfriend head into Brazil to study voodoo. The brother attends a voodoo ceremony and secretly records it.
While traveling, their jeep breaks down in the middle of nowhere and they meet a couple of hikers, who happen to be renting a plantation home a short distance away.
The brother goes to the plantation's cemetery, plays the voodoo tape and awakes a group of slave zombies who are seeking revenge.
It takes awhile for them to figure out there is evil afoot. When they try to escape in the jeep, the lunkhead boyfriend somehow drives off the road. Then the brother slashes all the tires, which oddly enough are fine the next day.
Terrible, terrible acting in this one and some accents that are hard to understand. The zombies are decent for a voodoo movie, but the best thing about the movie is the cover art.
