French Riviera, Winter 1992. Beautiful, reckless 19-year-old Vinca Rockwell runs away with Alexis, her philosophy teacher. No one will ever see them again. French Riviera, Spring 2017. Formerly inseparable, Thomas, Maxime and Fanny - Vinca's best friends - have not spoken in twenty-five years. But when they receive an invitation to their school's reunion, they know they must go back one final time. Because there is a body buried in that school. And they're the ones who put it there.
