While charming peat farmer Hannes Gerhards prepares for his girl Helen Dahms to move in from the city, his foreman finds and due to an overenthusiastic kid assistant ‘fails to hide’ a skull, indicating an old corpse. Police commissioner Lorenz Keller, whose grandson Jonas mentioned the ‘cool body’, was preparing to end his career, but believes this case may solve his most frustrating cold case. 15 years ago Fee, his daughter Jutta’s then 18 year-old schoolmate, went missing, never to be found. Keller’s bulldog zeal to close the case, suspecting Hannes of murder, upsets the whole town and his own family, but forensics is in for a long, arduous and surprising autopsy.
