Der Lehrer revolves around the teacher Stefan Vollmer (Hendrik Duryn) who teaches German, Science and PE.

His new school turns out to be very problematic with students hanging around in the halls and not listening to teachers.

With new and unconventional methods he finally succeeds to come through to his students and change their attitude against school.
