NASA must devise a strategy to return Apollo 13 to Earth safely after the spacecraft undergoes massive internal damage putting the lives of the three astronauts on board in jeopardy. 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.
