Un rendez-vous parfait pour Noel

Annie and Dave both end up at the same hotel after their flights are cancelled, and they spend a pleasant evening together. But the next day Dave misses his flight, and they don't reunite the next day as planned. All they know about each other is a first name and that they live in the same city. Still, both of them want to meet again. Separately, they begin searching for each other using the fragments they remember from their night at the hotel. It turns into an odyssey on both sides, as they grasp at one lead after another. But it proves extremely difficult - how will they ever succeed?
