A team of astronauts are deployed to the moon to prevent an asteroid impact on earth. However, the asteroid comes early and the whole crew has to evacuate. Due to an accident, maintenance worker Dugu Yue (Shen Teng) misses the evacuation notice from the leader Ma Lansing (Ma Li) and is left alone on the moon. When the plan fails, Lone Moon becomes the "last human in the universe" and began his life on the moon as a self-indulgent man.
