Ben works at a renowned publishing house in Paris and one day discovers a true gem among a pile of unsolicited manuscripts. However, the sender has only provided a postal address, so Ben travels to the 900-inhabitant village of Arnac-la-Poste, world-famous for its fairy-tale setting of a nostalgic Christmas world. There, he is met by a group of endearingly quirky residents and an unusual deal: he must bring a smile to the face of Laly, the willful daughter of the author, before the publishing contract can be finalized. But Ben is notoriously shy, and Laly is a woman who wants anything but to be saved.
