Lee Byeong-Gu is your common-all-garden sensitive blue-collar sci-fi fan who believes that alien beings have infiltrated human society masquerading as ordinary citizens. Convinced that his old boss is a high ranking xenomorph Lee kidnaps him and attempts to discover, by any means necessary, the invaders' nefarious plans. This is genre-bending insanity Korean style and, if you can follow the anarchistic narrative, you're a better man than me, but who cares when you've got more violent, crazy fun than you can shake a stick at?
