Following the success of his first feature "Django", Étienne Comar confronts with "Singing Jailbirds" the life in a prison for women with music and its capacity to unite people and a repertoire of international songs.

Little by little, this fragile balance, made up of lies, secrets and back and forth, cracks dangerously. Trapped, Judith chooses to head forward, at the risk of losing everything.
