劇情： April 2020 – Lockdown. Etienne, a film director, and his brother Paul, a music journalist, are confined together in their childhood home with their new partners Morgane and Carole. Every room, every object, reminds them of their childhood, and the memories of the absents - their parents, their neighbors…This compels them to measure the distance that separates them from each other and the roots they share, those of their ground zero. As the world around them is becoming increasingly unsettling, unreality, and even a disturbing strangeness, invades their daily gestures and actions.
