Mr. Müller isn't happy with his new job at the Goethe-Gesamtschule. The early becoming upward and adjusting assessments annoy him. Because she wishes to be always a symbol of the firm, director Gerster would like to develop the image of this Goethe-Gesamtschule. To do this, she wants to take the partnership out of the Schillergymnasium away with a Thai school. Therefore, Mr. Müller, Mrs. Schnabelstedt and the 10b must proceed on a school excursion to Thailand.
