In each episode, one Flemish celebrity, from any walk of life (actors, presenters, singers, other show- and TV-personalities, politicians, sports(wo)men, even a cardinal and a astronaut) is received to be confronted in a 'classroom' studio set with his past in the form of his former classmates, mainly reminiscing about their schooldays and finding out what happened later to each of them in adult life, as few keep in touch.—KGF Vissers
