Four wine experts, each at a crucial point in their lives, arrive at a French vineyard estate for an unforgettable experience --- but not the kind they expected. Avery gave up her hard-won but exploitative sommelier job to come, while wine prodigy Cosmo is trying to disguise that his life is in freefall. Millionaire Sonny owns a tacky wine brand and can't help aggravating Cosmo, while caustic magazine writer Maëlys hovers with her pen poised. It seems at first that these four have little in common except for their love of wine. But, as the quartet awaits the penultimate night of the trip, when they will taste the only bottle of one of the rarest wines in the world, it becomes clear that each of them grapples with a private crisis. Each projects their ultimate hopes and fears onto the contents of this bottle, a bottle rendered divine by age and scarcity.
