NASA astronauts and former Marine Kira Foster embark on a mission to the International Space Station (I.S.S.) alongside fellow American astronaut Christian Campbell. Once aboard, they encounter their teammates: American astronaut Commander Gordon Barrett and Russian cosmonauts Weronika Vetrov, and brothers Nicholai and Alexey Pulov. Despite language barriers and cultural differences, the Americans and Russians form a cohesive team. Gordon and Weronika even kindle a romance. However, their peaceful existence shatters when Kira observes massive nuclear explosions across the United States from the I.S.S. Communication fails, and the U.S. government orders Gordon to take control of the I.S.S. “by any means necessary”. As the station orbits dangerously low, the crew faces a critical deadline: aid must arrive within 24 hours, or they risk plummeting to Earth’s surface. Amidst the chaos, Nicholai secretly sabotages the mission, leading to a shocking betrayal. Weronika, devasted by the loss of her lover, devises s desperate plan to survive.
