A hiker is found dead in a remote forest that is popularly known as the "Murder Hole". Opposite the victim is a melting snowman with one eye missing. The start of a series of murders in the forest area near Freudenstadt. The handwriting is always the same: all victims show frostbite, while the left eye is covered with a black gem. The investigative team Maris Bächle and Konrad Diener has Florentin Sneelin in its sights, a reproductive doctor who lives in a romantic moated castle whose ice cellar not only stores champagne. The suspect knew the victims from a stay in a children's home many years ago. The teachers there enforced discipline and order using sometimes sadistic methods. Their wards did the same. There was a strict caste system among the children. Sneelin belonged to the lowest caste. He was a so called "Snow Child", one that his mother wanted "to foist" on his father.

Not everyone deserves a second chance. The experienced investigator Wallat is sure of that - and certainly not the child murderer Hagenow, who is released after 15 years in prison, although he is still considered dangerous. Wallat takes over the management of an LKA team that monitors the potential repeat offender. His "unofficial" assignment does not fit into any service manual: Wallat is supposed to catch Hagenow in the act - in good time, of course - in order to put him behind bars forever. Meanwhile, the ex-convict moves into a room in the house of the idealistic village pastor Berkenbusch and starts a job at the local sawmill. The LKA team serves him around the clock. When Wallat loses sight of him during a night walk, a nightmare begins the next morning: Max, the eight-year-old son of Berkenbusch's housekeeper, has disappeared without a trace
