Byeong-gu believes that the world is on the verge of an alien invasion, and sets out to save the world.
Why do so many movies fall apart in the final reel? Jeong's excuse is that this is his debut, but with a little restraint he could have pulled off a madcap coup with this ambitious blend of sci-fi and serial-killing slapstick.

Sci-fi slapstick that falls down at the final hurdle. What could have been a coup is instead a marginal win.
