Plot
Twin brothers Zip and Zap are sent to the summer school Hope, a re-education centre ran by strict Falconetti, who forbids all forms of recreation and entertainment. When Zap gets in trouble for disrupting a class, he is locked in the "Isolation Room" where he is told to think about what he has done. While there, he finds a bag of marbles hidden in the room, and forms the "Marble gang" with several other students in the school: Filo, Micro, and Matilda, who is Falconetti's niece; the gang performs a variety of pranks, including the vandalising of the statue of Sebastian Hope, the school's founder. They always leave a single marble at the site of their prank.

When Falconetti attempts to stop the vandalism, he accidentally breaks the part of the statue, revealing a map that shows a path to hidden diamonds under the school. Zip and Zap steal the map from his office and follow the map's clues while they are pursued by Falconetti. The Marble Gang end up in a room full of toys, and Zap considers that the "diamonds" in the map were really just a reference to Sebastian Hope's diamonds – his toys. Falconetti finds them, then reveals that the school was originally a school of play and toys ran by Hope, until Falconetti bought over the school and transformed it to please his father. Falconetti locks them in the room of toys, but Micro notices a machine where they insert several toys they picked up while exploring the school. Music starts playing around the school and the students and teachers discover it is coming from the statue of Hope. The underground room Zip and Zap were locked in starts spiralling up into the main garden in front of the school, where all the students and teachers are gathered. The other students start cheering on the Marble Gang, and another teacher punches Falconetti and tells the other teachers to lock Falconetti until the police arrives. The movie ends with Zap recollecting how "we never found the diamonds, but it was the best summer we ever had," and the five members of the Marble Gang all holding their last marble together, than tossing it into the air. The diamonds are revealed to have been hidden in the marble.
