The Súnion secondary and high school opened its doors to the documentary's filming. It shows how students organize themselves into self-managed groups of eight adolescents. They constitute a "natural group," their basic functioning unit. Throughout the school year, hundreds of students aged twelve to eighteen decide with whom to form a group, work, organize, and share time, classes, and tutoring. These decisions and dynamics confront them daily with the reality of their relationships, their integration or distance with other people, and their strengths and weaknesses at a stage where all their values ​​are in construction.
