In this tense psychological drama, Judith (Virginie Efira) leads a secret double life split between two households in two countries. In Switzerland, she lives with Abdel (Quim Gutiérrez), with whom she is raising a little girl. In France, she lives with Melvil (Bruno Salomone), with whom she has two older boys. Gradually this fragile balance, based on lies and back-and-forth trips, begins to veer dangerously off the rails.
