Welcome to the future. Civilization has been obliterated by natural catastrophes and global economic collapse. In the rotting skeletons of once great cities, the remnants of mankind struggle to survive under the brutal reign of vicious warlords who rule by fear and the power of the fist. The only hope for a courageous band of street urchins is the brave fighter Jonas, the last surviving keeper of the secrets of an ancient martial arts dynasty. Jonas must challenge the heartless Bosco in a fight for freedom or death ... only then can he become master of mankind's destiny.

Juliane Kostner is an attractive woman in her prime: charming, fashion-conscious, worldly. It's no coincidence that she has been head buyer at a luxury department store in Berlin for 30 years. Juliane's private life, on the other hand, is not quite so rosy. Single Juliane doesn't have a particularly trusting relationship with her grown-up daughter Henrike, for example. But when Henrike, who is heavily pregnant, has to go into hospital after a fainting spell, her husband, the busy pilot Martin, has no choice but to ask Juliane for a favor: She is to look after their two grandchildren for the duration of Henrike's stay in hospital.
