Gyalogbéka (1985)

A group of sixth-graders decide not to go to the summer camp provided by their school at Lake Balaton, but rather to organize an Indian-themed camp for themselves in the mountains. Most of the teachers are opposed to this, of course, but the school principal assures them of his support. As camp leader, they find a soldier they knew already, who initially ruins their vacation with excessive discipline. But over time, they learn to respect each other and form a good team.
