In the near future, humanity has achieved remarkable milestones in space exploration. Astra, an experienced astronaut, leads a mission beyond our solar system to investigate a mysterious anomaly known as the "Celestial Abyss." When the spacecraft approaches the anomaly, an energy explosion destroys it, leaving Astra alone and stranded in deep space, light-years away from Earth. Without communication or navigation systems, Astra must battle loneliness and despair while trying to survive in the vast cosmos. His determination drives him to repair the spacecraft and face the difficult decision of using the anomaly's power to return home, even if it may disrupt the balance of the universe.
