The school bus that picks up 11 kindergarten and elementary school children is hijacked right on the day of the carnival which requires them to wear clothes as they wish. Mr Rodi, who is usually called Uncle Duck (Aziz Gagap), because his bus horn sounds like a duck, is sedated with the nanny of one of the children. The children try to save themselves. They manage to escape from the bus. Adventures in the forest make them experience various events.
