Three generations of women untangle a complex family history that spans both world wars and reveals unexpected insights about marriage and fidelity.
 
Christiane, eighty-six years old with a vibrant sense of humor, lives alone in a large apartment in the heart of Paris. Her daughter, Catherine, could not be more different; sullen and uptight, she resents her unfaithful Milanese husband. After discovering yet another affair, Catherine takes refuge in Paris at her mother’s home, accompanied by her own daughter, Luna. Christiane, who in spite of occasional dalliances lived a beautiful love story with her late husband, uses all of her freethinking charm to try to wean Catherine of her rigid self-pity.
 
While listening to her mother and grandmother, Luna becomes increasingly curious about Christiane’s aristocratic Catholic background, prompting Christiane to tell the story of her father’s war experiences and the devastating love affair that brought chaos to the whole family. As memories resurface, the present takes on a different dimension.
 
With a keen, lighthearted wit, The Devil’s Reward shows that life may be complicated and often painful, but if conventional morals prevail, it becomes unbearable.
