Helen, Rose and Lili have survived the Holocaust and have never seen each other since the war has ended. In 1960, they meet again in Berck, France. They learn to enjoy together simple pleasures in life: nice meals, ballads on the beach, playing in the waves.

Simon Eskenazy is a gay Parisian clarinet player who lives his single life to the fullest. One day, he receives a very tempting offer from his homophobic uncle, looking to continue the family legacy – if he gets married and has a child, he will receive ten million francs and inherit his uncle's luxurious mansion. After meeting Rosalie Baumann at his cousin David's wedding, and with some convincing on his mother's part, Simon sees an opportunity to fulfill his uncle's wishes and the pair go ahead and get married, but not before traveling to New York to meet Rosalie's Orthodox Jewish family. As Simon tries to develop real feelings for Rosalie, he struggles with his feelings for his newlywed cousin David.
