Detective Inspector Lisa Becker is fuming: Her bathroom scale is becoming more and more impertinent, the nice guy next door is too intrusive, her sexy colleague is not intrusive enough, an alley cat has moved into her apartment - and then there is this serial killer who beheads people in their sleep. Who needs that? There seems to be no connection between the murders. The killer could be insane, choosing victims at random. Lisa is convinced that that's not the case, and after lots of digging she finds the motive... An unconventional thriller from Berlin, full of irony, an offbeat detective and lots of blood-covered carpets.
