Overview
The Serpent and the Rainbow is a 1988 American horror film directed by Wes Craven and starring Bill Pullman. The script by Richard Maxwell and Adam Rodman is loosely based on the non-fiction book of the same name by ethnobotanist Wade Davis, wherein Davis recounted his experiences in Haiti investigating the story of Clairvius Narcisse, who was allegedly poisoned, buried alive, and revived with a herbal brew which produced what was called a zombie.
Plot
In 1978, a Haitian man named Christophe mysteriously dies in a French missionary clinic, while a voodoo parade marches past his window. The next morning, Christophe is buried in a traditional Catholic funeral. A mysterious man dressed in a suit who was outside Christophe's hospital window on the night he died is in attendance. As the coffin is lowered into the ground, Christophe's eyes open and tears roll down his cheeks.
Seven years later, Harvard anthropologist Dennis Alan is in the Amazon rainforest studying rare herbs and medicines with a local shaman. He drinks a potion and experiences a hallucination of the same black man from Christophe's funeral, surrounded by corpses in a bottomless pit.
Back in Boston, Alan is approached by a pharmaceutical company looking to investigate a drug used in Haitian Vodou to create zombies. The company wants Alan to acquire the drug for use as a "super anesthetic". The corporation provides Alan with funding and sends him to Haiti, which is in the middle of a revolution. Alan's exploration in Haiti, assisted by Dr. Marielle Duchamp, locates Christophe who is alive after having been buried seven years earlier. Alan is taken into custody, and the commander of the Tonton Macoute, Captain Dargent Peytraud—the same man from Christophe's funeral and Alan's vision in the Amazon—warns Alan to leave Haiti.
