 Based on the true story of the ill-fated 13th Apollo mission bound for the moon. Astronauts Lovell, Haise and Swigert were scheduled to fly Apollo 14, but are moved up to 13. It s 1970, and America have already achieved their lunar landing goal, so there s little interest in this "routine" flight.. until that is, things go very wrong, and prospects of a safe return fade.
