Le braconnier de Dieu (1983)

A monk for thirty-seven years, Brother Gregory cannot resist temptation. Leaving the monastery for the first time to fulfill his duty as a voter, he catches up with pastis and women - The doors of a new existence open to him. Back to civilian life, Gregoire finds refuge in a farm where he meets a degenerate viscount, a nymphomaniac bigot, a German, forgotten there since the last war, and a merry band of drunks that he diverts from the bottle thanks to a miraculous water from Lourdes.
