Violette Toussaint is a beloved cemetery caretaker. Passers-by and regulars come to warm themselves in her home, where laughter and tears mingle between cups of coffee. Her daily routine is punctuated by their confidences. One day, a man knocks on her door. His name is Julien Seul and he is a police commissioner who has questions about a couple resting in the cemetery. His investigation begins and the links between the living and the dead come to light, and some souls thought to be dark turn out to be bright.
