Overview: The village suffers an epidemic of diarrhea. Dr. Elsenbosch suspects the swimming pool, next the water cleaning plant, but while he has them closed down, tests prove neither to be the cause. Meanwhile plumber De Groot is selling bottled water, to pay for his doted boy's plans to study ICT, despite his dearest wish being for the knave to succeed him. Unvoluntarily retired on medical grounds, music teacher Wieger Troost asks for an antedated diagnosis to claim a pension after all, but is also offered a part time position. The village constable is lonely.
