The short stories of Guy de Maupassant enjoyed a renaissance in the early 1950s, thanks in great part to the Max Ophuls production Le Plaisir. In Trois Femmes, three De Maupassant stories are dramatized, each conveying the central theme of women falling in love. In the first, a black female carnival entertainer causes an uproar when she falls in love with a white soldier. In the second, a young bride is pressured into having a baby to collect a huge inheritance. And in the final episode, a pregnant girl is "adopted" and protected by a small circle of friends. In standard De Maupassant fashion, each of the three stories in Trois Femmes is capped by a surprise twist.
