Keri Russell plays Katie Armstrong, an American student in Germany studying criminal psychology. She chooses a notorious subject for her thesis: the cannibal killer Oliver Hartwin (played by Thomas Kretschmann). Oliver dreamed of eating a willing victim, and thanks to the internet, he was able to find a volunteer, a young man named Simon Grombeck (played by Thomas Huber).
The story is told in flashbacks as Katie researches these men and their pasts. Events culminate in Katie's discovery of a snuff tape that documents the crime.
