Armin Meiwes is a German computer repair technician who, in 2001, killed and ate a man he found through an internet ad. The film reconstructs the case from what is publicly known: Meiwes posted on a site called The Cannibal Cafe seeking a well-built man willing to be slaughtered and consumed, and Bernd Jürgen Brandes, an engineer from Berlin, answered. The two met at Meiwes's home in Rotenburg on 9 March, where Meiwes amputated Brandes's penis, the men attempted to eat it together, and Meiwes eventually killed him with a knife in a room he had built for the purpose, the Slaughter Room. Nearly all of it was recorded on a two-hour videotape that has never been made public, though journalists who viewed it describe its contents in detail. Meiwes stored the remains in his freezer under pizza boxes and ate roughly 20 kilograms of flesh over the following ten months. The film treats the case less as shock material than as a psychological puzzle: how consent, isolation, and fantasy converged into an act neither man's advertisement fully explained.
