On the eve of summer vacation, Prune leaves her parents for the traditional "end-of-year school trip." But once she's gone, an incredible snowstorm hits the small town where her family lives. Philémon, her younger brother, then makes an astonishing discovery: an Inuit family has settled on a roundabout. The meeting of these two worlds sets the stage for a wonderful adventure.
