Dr. Evelin Wolf and Alex Gutenberg

Some deserve to live. Others deserve to die. A lunar eclipse hovers above Hamburg and bathes houses and streets in an unearthly light. In the exclusive district of Blankenese, four men are brutally murdered in the basement of a villa. Only the granddaughter of the owner survives the bloody massacre. Severely traumatized and completely listless, she is found sitting in the middle of the corpses. She cannot remember anything. Assistant District Attorney Alex Gutenberg, who has to struggle with a number of personal issues himself, asks the criminal psychologist Dr. Evelin Wolf for support.

Some scars hide dark secrets. Who are you? Hamburg criminal psychologist Dr. Evelin Wolf ponders, as she examines the mentally disturbed homeless man with the conspicuous scar on his face. The extremely aggressive man with no memory and no identity is said to have committed a brutal murder. But Evelin and Assistant District Attorney Alex Gutenberg doubt his guilt and suspect that there is much more to the supposedly crystal-clear case. Shortly afterwards, Hamburg is shaken by a series of murders that are unsurpassed in their cruelty and sadism.
