Scientists make a shocking discovery: a massive asteroid is hurtling toward Earth, threatening humanity with extinction. To avert disaster, mankind launches the ambitious “Lunar Shield Project.” Dugu Yue (Shen Teng), a maintenance worker stationed on the Moon, secretly harbors feelings for the brilliant and fearless commander Ma Lanxing (Ma Li), who barely notices him. When a meteor shower strikes earlier than expected, the lunar base is hastily evacuated—leaving Dugu Yue behind. Stranded on the desolate Moon with only a bad-tempered kangaroo for company, Dugu Yue embarks on an extraordinary fight for survival.
