Smart Max and his friend Tüte are excited about a robot who has many talents, including a gift for mathematics. They steal the robot from an exhibition and take him home so he can help with their homework. But the robot turns out to have a mind of his own due to faulty programming and is soon on the loose around town.

Smart Max sets out to catch the robot while Tüte buys time by playing the robot in the exhibition. But he cannot solve the math problems and makes a fool of himself. Luckily, Smart Max shows up with the robot at the last minute. The boys decide that they will do their own homework in the future.
