A murder in Paris’ Louvre Museum and cryptic clues in some of Leonardo da Vinci’s most famous paintings lead to the discovery of a religious mystery. For 2,000 years a secret society closely guards information that — should it come to light — could rock the very foundations of Christianity.

Jean-Baptiste Poquelin is raised by his father and his grandfather because his mother dies when he's still very little.

In a French prison, three men are coming to terms with the emotional and physical torment which their incarceration brings them. Arnaud is serving a six-month sentence for drug smuggling; he protests his innocence and will do anything to secure an early release. Francky is a hardened criminal who has all but lost his wife and family and who seeks comfort in self-inflicted abuse. Kader is in prison for theft; he is the most philosophical of the three men, he is growing accustomed to prison life and seems to prefer it to the world outside.

Not long before World War I, in a French Alpine town near the Italian border, a pack of slaughtered wolves is delivered to local taxidermist Leon (Patrick Chesnais). A surviving black cub comes down from the mountains looking for his family, and is saved from discovery and certain death by Leon’s young daughter Angele, who releases him back into the wild. The Great War comes and goes, making local foundry owners the Garcins rich. Family patriarch Albert Garcin (Michel Galabru), who happens to be Angele’s godfather, has given a free lifetime’s lease of a shack in the hills to a gypsy woman (played in flashbacks by Elisa Tovati in which she’s seen, literally, having dances with wolves on stage). Her son Guiseppe (Stefano Accorsi), who appears to be slightly mentally handicapped, guards the wolves he’s befriended up there, especially the black pack leader he calls Carbone.

A girl on the verge of maturity tells her family and friends in the French countryside so many lies about her hidden relationships that they can hardly be called 'white lies' anymore. It gradually becomes clear what secret she's bearing with her.

She leaves Pollak and returns to Prague with her father, where she befriends and translates Kafka.

Someone we hear talking - but whom we do not see - speaks of a project which describes the four key moments of love: meeting, physical passion, arguments/separation and making up. This project is to be told through three couples: young, adult and old. We do not know if the project is for a play, a film, a novel or an opera. The author of the project is always accompanied by a kind of servant. Meanwhile, two years earlier, an American civil servant meets with an elderly French couple who had fought in the Resistance during World War II, brokering a deal with a Hollywood director to buy the rights to tell their story. The members of the old couple's family discuss heatedly questions of nation, memory and history.
