On the last day of school, teachers and students have only one thing on their minds: finally, vacation. Corinna, the daughter of a prefabricated house manufacturer, has failed to pass her exams despite all her father's attempts to bribe her. With a little trick, her classmates want to fulfill the greatest dream of Corinna's teacher, Dr. Markus. A quick spin of the wheel of fortune and he has won a prefabricated house in a competition. Everything seems to be going well, but suddenly the deception is revealed.
