Leon, an unemployed theater director, is about to lead a drama class in a maximum-security prison. He desperately needs the money. Together with Jean, an actress who happens to be his ex-wife, and Alice, a young and inexperienced social worker, he arrives at the first class only to discover that just two inmates showed up: Kevin, a hot-headed young man, and Angel, a silent prisoner in his mid-fifties.
Thus begins a hilarious, turbulent, and moving journey. The intersecting fates and revealed stories show us that even within prison walls, the world remains vast and surprising, and that imagination has unexpected ways of setting us free.
