A single day in Paris changes the lives of three Americans as they each set off to explore the city with a French tutor, learning about language, love, and loss as their lives intersect in surprising ways.

Josie, Riley, and Jeremy have come to the City of Light for different reasons: Josie, a young high school teacher, arrives in hopes of healing a broken heart. Riley, a spirited but lonely expat housewife, struggles to feel connected to her husband and her new country. And Jeremy, the reserved husband of a renowned actress, is accompanying his wife on a film shoot, yet he feels distant from her world.

As they meet with their tutors - Josie with Nico, a sensitive poet; Riley with Phillippe, a shameless flirt; and Jeremy with the consummately beautiful Chantal - each succumbs to unexpected passion and unpredictable adventures. Yet as they traverse Paris's grand boulevards and intimate, winding streets, they uncover surprising secrets about one another - and come to understand long-buried truths about themselves.
