Knallhart plot
Fifteen-year-old Michael Polischka (David Kross) moves to a working-class neighborhood with his mother (Jenny Elvers). The tough mentality that prevails there is very different from that of the chic suburb where he used to live. Aggression and extortion by a violent gang make going to school hell for him. His home situation isn't much better as he has to deal with the new sweethearts of his mother who is desperately looking for a new man. However, his life takes a new turn when the criminal Hamal (Erhan Emre) takes him under his wing. Michael's innocent demeanor makes him the right person to deliver drugs to local dealers. The teen handles the pressures of these assignments very skillfully. Michael proves he's tough enough, but in the end he also realizes he's in an extremely dangerous position.
