Rosh Gadol

A group of 13-year-olds should invent a project for the young entrepreneurs competition at the school. Tomer, the leader of the group, decides to invent a missile (even though it is dangerous). After the missile lands on Elchanan's office, Tomer is suspended from the project. When he returns (after his father activated some sort of protekia) there is already a new leader for the project.
