In French Leave four siblings are reunited one afternoon after skipping out on a dull family wedding. They leave behind needy spouses, annoying relatives, and the dull demands of encroaching adulthood for one final, riotous and joyous adventure in each other’s company.

Garance, her sister Lola, brother Simon and his overbearing wife are driving through the French countryside on their way to a family wedding in Podunk-on-Indre. Once they arrive and discover the real occasion to celebrate is the fact that they are together again, the three siblings realize what they really want to do is visit their youngest brother Vincent, who is working as a tour guide at a château in the heart of the enchanting province of Touraine. The siblings jump back in their car and race away, then talk Vincent into playing hooky in order to all hang out like they used to.
