What does a passionate actor do who can barely make ends meet due to a lack of good role offers? Etienne (Kad Merad) takes over the management of a prison theatre troupe to give it a new lease of life. After all, it can't get any worse than unemployment. And what play could be more obvious than "Waiting for Godot" - if there's one thing the inmates have learned, it's that. Etienne is amazed at the acting talent that lies dormant in his protégés. If everything works out, there's even the prospect of a tour outside the prison walls.
