A psychological thriller about a man who is sometimes controlled by his murder-and-mayhem-loving alter ego.

Ten strangers are summoned to a remote island and while they are waiting for the mysterious host to appear, a recording levels serious accusations at each of the guests. Soon they start being murdered, one by one. As the survivors try to keep their wits, they reach a disturbing conclusion: one of them must be the killer.

When a notorious German serial killer is captured after committing some of the most heinous acts against humanity ever imaginable, a farmer and police officer from a sleepy rural community on the outskirts of Berlin is drawn into the case as he searches for the answers to a murder that has shaken his tight-knit community.

A lawyer is asked to come to the police station to clear up a few loose ends in his witness report of a foul murder. "This will only take ten minutes", they say, but it turns out to be one loose end after another, and the ten minutes he is away from his speech become longer and longer.
