Popolar gymnasium (high school) principal Meike Daschner is hospitalized after electrocution by door under current, after stepping into a water balloon puddle, all part of the sixth formers' authorized end of term prank orgy. Perhaps the intended target was unpopular janitor Jürgen Jahn, who raises his sixth former daughter -alone on the flat that goes with the job. The ream focuses on the prank feast organizing committee: klutzy Jannis Schröder, who has a beef with Jahn, and Tamina, Pauline's arrogant but crafty buddy. Helpfully knowledgeable is even more ambitious school paper editor Tim Baaske.
