When the doorbell rings one summer afternoon, Camille, a single mother and architect, answers it, expecting the babysitter for her five-year-old daughter, Elsa.

But when the babysitter fails to materialize, Camille has no choice but to leave her daughter with the girl’s estranged father, releasing the pair on a three-day adventure that thrusts an ill-prepared Antoine abruptly into parenthood.
