Behindert sagt man nicht!

Mr. Schön, principal of the Three Oaks Special School, has ordered the transfer to the local comprehensive school for eighth-grader Justin. Not because Justin's performance has improved, but to get rid of him as quickly as possible. Justin feels shunted off to the unloved comprehensive school and, with the help of his classmates Hendrik, Noah, Pascal and Leila, tries to prevent him from being sent back to school. The disperate group is united by the fact that they all have a difficult relationship with their principal and finally want to get one over on him. Their plan is to kidnap the principal's prize-winning male Havanese and trade him for Justin's freedom. Each student brings a special skill to the decisive coup, based on their respective special needs. It quickly becomes clear that the students imagined blackmailing the principal a little too easily: Will their plan work out?
