Bloody-Disgusting.com has posted the official synopsis for Ruggero Deodato's new Cannibal Holocaust film. To quote:
The film is about Professor Harold Moore, a New York anthropologist traveling to the wild, inhospitable jungles of South America to find out what happened to a documentary film crew shooting a film about cannibal tribes.
Deodato directed the original Cannibal Holocaust, released in 1980. Despite the similarity in plot, this new film is not being described as a remake, but as a "companion."
