Witnessing how she turns around a humiliating situation, younger sculptor Antoine becomes so smitten that he breaks up with his fiancée and sets out to win Angèle's heart. Meanwhile, Angèle attempts to quash the budding romance of her young co-worker, Marie, and a much older widowed client, despite their obvious rapport.

In the woods, a 13-year-old boy is grabbed by an escaped convict and told to bring money later that day. The boy does as he's told, only to be attacked by the convict's partner.

All this takes place in four days during which the boy has his first communion, his separated parents face each other amidst grandmother's hopes they'll reunite, the grandfather just wants to go fishing, the school's chaplain complains about the boy's behavior, and the convicts' shared girlfriend comes, gun in hand, to help them escape to Tangier. The mother's surprising decisions complete the story.
