One day in the City of Light.
One night in search of lost time.

Paris in the interwar period is teeming with artists, writers, and musicians, a dazzling melting pot of genius. Among the city's bright and famous residents, four ordinary people are each searching for something they have lost.

Suren Balakian is an Armenian refugee who makes a living performing puppet shows. His beloved marionettes cannot protect him from the demons that chase him in the dark shadows of the night. In the end, they always find him in his dreams. Guillaume Blanc has stopped painting in recent days because he wakes up with his heart pounding in his chest and his breath coming out short and wild. He owes twelve hundred francs and has six in his pocket!

Jean Paul Mayard loves America and interviews Americans living in Paris. He wants to live there but hasn't decided because he is searching for his daughter. He constantly looks around, even though ten years have passed. Camille Clermont was Marcel Proust's housekeeper. He had asked her to burn his notebooks, but she kept one… and now it has disappeared.

When the paths of the four protagonists cross on that fateful night at the Le Chat Blanc cabaret in Montmartre, the invisible threads that connect them are revealed.
