Ornithophobia

Murder is in the air, a mystery's trail is marked with feathers and it's quickly running cold. Cheol-Min Han is an office worker who suspects that he's losing his mind...or is he seeing the truth for the very first time? Who are these bird-faced, bloodthirsty creatures he's confronted with? Why are they hunting him? Where do they come from? What do they want? Who will believe him? Most importantly, how will he survive?
