On a cold Parisian morning, a man named Alain Leroy wakes up in a hospital room after attempting suicide. Disoriented and burdened by the weight of a life that seems to have no meaning, Alain delves into his memories as he reflects on his past relationships and his search for purpose. The bohemian lifestyle he once led, filled with parties, womanizing, and intense emotions, now feels empty and desolate.
Alain decides to leave the hospital and return to his old life in an attempt to reconnect with friends and former lovers. He reunites with an ex-girlfriend, whom he still loves, and who appears to be trapped in her own routine. Together, they try to revive the happy moments of the past, but the shadow of disillusionment looms over them. As Alain explores his life, he feels caught in a world that is increasingly alien to him, filled with unfulfilled promises and frustrated desires.
With the backdrop of the City of Light, the film transforms into an introspective journey about loneliness and the longing for connection in an increasingly superficial environment. Alain searches for answers to questions that seem to have no solutions, trapped in an internal struggle that reflects the complexity of human existence. In the end, his quest to find meaning among the lights and shadows of his life could lead him to irrevocable decisions.
