Somewhat based on the true-life experiences of ethnobotanist Wade Davis, this provocative horror outing is set in Haiti and offers a fascinating look into the voodoo cult and the making of zombies. Davis' book was a serious examination of the zombie phenomenon, but the film adds plenty of horror elements to sensationalize it. He was sent to Haiti by a drug company to see if there was a pharmacological explanation for the walking dead, but once there, he finds that the practitioners and the locals will do anything to keep him from learning their secrets.
