Jean is a Parisian fashion photographer haunted by past choices-he deserted his family and career in the City of Light and escaped to bustling New York. There, he meets Tanya, a stunning model afflicted with a grave illness. They fall into a passionate, fragile love-one that burns bright but is shadowed by mortality.
Meanwhile, across the Atlantic, Jean's life takes a cruel turn. His daughter, Sophie, falls ill back in Paris and dies, driving Jean into spiraling grief. Consumed by guilt and loss, he abandons everything he once cared for and retreats into madness.
Determined to rescue him, Tanya journeys to Paris, offering hope and solace. For a fleeting moment, Jean regains his balance. But tragedy strikes again: weakened by lingering self-loathing and a night of heavy drinking, Jean loses control of his car-tumbling into the cold Seine. His death is sudden and brutal.
Unable to bear life without him, Tanya returns to the riverbank and plunges into the same waters, choosing death over a world without Jean. In a heartbreaking finale reminiscent of doomed lovers like those in Les Amants du Pont-Neufen, they find eternal unity in the river's depths.
