In a post-apocalyptic future, humanity stands on the brink of extinction after a devastating nuclear war. Survival has become a constant challenge for the few remaining in Paris, now shrouded in shadows, ruins, and a desolate atmosphere. A prisoner, chosen by a group of desperate scientists, becomes the subject of a bold experiment: time travel. The scientists believe that by accessing a moment in the past, they will be able to find enough resources to save humanity.
The prisoner is haunted by an image that torments him: a scene from his childhood, where he witnesses a man's death at Orly Airport. This memory becomes his anchor, a point of connection between the bleak present and a lost past. As he is sent back in time, reliving those moments, he encounters a woman, a love that blossoms in a time that does not belong to him. Through journeys and memories, the story delves into the exploration of time, memory, and love, while the prisoner seeks answers for the future of his world.
However, with each journey, the line between reality and the temporal grows thinner, leading the protagonist to a crossroads that challenges his understanding of time and existence. In his struggle to change fate, he faces the inevitable question: can one truly alter the course of time without paying a price?
