This is the story of "Roland" who spent long years in jail. He often tried to escape and succeeded six times in doing so. He played his own part in Jacques Becker’s film "Le Trou". His story is told here by two voices, his and his daughter’s.

Four prison inmates have been hatching a plan to literally dig out of jail when another prisoner, Claude Gaspard, is moved into their cell. They take a risk and share their plan with the newcomer. Over the course of three days, the prisoners and friends break through the concrete floor using a bed post and begin to make their way through the sewer system -- yet their escape is anything but assured.
