Stefan Vollmer is an unconventional teacher in every sense with some highly unorthodox teaching methods. Vollmer returns to his career as a geography teacher after a period of absence and ends up with one of the lowest performing and hardest to manage classes in the school. While all the other teachers have given up hope of ever getting anyone in the class to improve their performance, Vollmer rises to the challenge. As he tries to control an eclectic bunch of unruly teenagers, Vollmer seems to be his own worst enemy, and trouble lurks around every corner with some uproarious scenes along the way.
