The Gang Next Door Dec 18, 1980

A gang of city children is secretly practicing to enter a musical competition. All of them plunder their parents' supplies in order to build their own stage and amplifiers. Baffled by these unexplained thefts, the parents decide to hold a meeting as their suspicions turn to a group of camper folks living across from their flat. The tables are turned when the residents take a camping holiday of their own and end up being mistrusted by the locals as much as they themselves did their own neighbors. Meanwhile, the children's gang meets a rival group of kids who are planning to enter the same competition.
