The series revolves around the life and adventures of Luc and Theo, two best friends in the 8th Grade who get stuck in a time loop where every day is the same Monday. Since the events of that day are always the same, the two know what will happen where and when. They use this knowledge as an opportunity to do whatever they want, especially at school and/or what usually gets them in trouble.
