Monsignor Renard tells the story of the German occupation of France during World War II through the eyes and experiences of a humble and extraordinary priest -- a man of profound faith whose beliefs are tested to the breaking point as he is forced to choose between the peaceful teachings of the Christian doctrine and the violent necessities of the emergent Resistance.

Returning home to family and personal conflicts, Renard (John Thaw, Inspector Morse, Goodnight Mister Tom) is faced with many moral dilemmas. Renard's faith tells him he must minister to friend and foe alike, but, as he finds himself drawn to the side of Free France, the threat to his personal safety increases as the Germans try to unmask the members of the Resistance. The good priest must summon every ounce of courage, strength and faith he possesses to carry everyone through the storm of evil that lies ahead.
