Everyone has their hidden secrets, which they have taken care to store in a box of which they alone have the key. Secrets so strong, surprising or moving that we want to share them! For an evening, Faustine Bollaert offers to open the box of three artists in order to discover their secrets. Mimie Mathy will explain to us why Bourvil's song "La Tendresse" has a special meaning for her. Olivier Minne's mother will look back on her son's childhood, of which she is very proud. Sheila will look back on her childhood when she sold brioches in the markets with her parents.
