On December 23, the holiday season is in full force and the destinies of strangers intertwine: a hardened bachelor wants to find love; a couple expect their first child; a singer returns to the stage after a break; a mother tries to organize the perfect Christmas; a teen carries a big secret; a man struggles with the modern world; and the new manager of a large hotel must prove her worth.

Etienne (10 years old) and his little brother David (7 years old) share everything: their room, their toys, but especially their unbridled imagination. When David mysteriously disappears, Etienne, with the help of his friends, tries to prove that he has been abducted by aliens.

A group of kids gather to compete in the annual soap box race down the village's highest peak.
