Gambit (2005)

A young couple on a gloomy quest to find each other, trapped in a confined space, in a car, on a winter trip to a vacation destination that is supposed to give their relationship a new kick. Silence and trivialities prevail in this standstill of the relationship. Only the woman's transformation in a gas station restroom from a conservative woman dominated by him to a self-confident and lascivious hitchhiker brings the actual desires and passions of the two to light.
