In 1962 in Haiti, Clairvius Narcisse was certified dead and buried. Days later, he was raised from the grave by a sorcerer and became a will-less zombie slave. In 1980, a Haitian psychiatrist found him. In 1983, a Harvard ethnobotanist discovered the secret of his poisoning. And in 1985, a reporter traveled to Haiti to (literally) unearth the true story.
