From November 2018 to May 2019, nine long-sentence inmates from the Meaux-Chauconin penitentiary will take part in a theatrical creation directed by choreographer Hervé Sika with the collaboration of professional artists and the Orchestre de chambre de Paris. From boxing sessions to writing workshops and dance rehearsals, right up to the final performance at the MC 93 in Bobigny, and despite the doubts and hazards of working in a prison environment, a surprising show will emerge that will have a profound effect on the participants.
