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.
The Harz village policeman Frank Koops cares little about adventures and even less about birthdays.

The four friends Musti (Reza Brojerdi), Hannah (Lea van Acken), Yannick (Jerry Hoffmann) and Tom (Lucas Reiber) could not be more different. But they have one thing in common: They are all pretty nerdy misfits who only just survived school thanks to their mutual support. For graduation, they want to prove it to everyone and promise nothing less than the craziest party of the year. However, the closer the legendary party gets, the more the friends realize that there seems to be something between them. Be it unspoken feelings, hurt pride or fear of the future. When the big day of the party finally dawned, the four of them were no longer just about celebrating, but about saving what is most important to them: their friendship!
