There are things in this world that we don't understand. That is why Chicago is a ghost town right now. Creatures have been popping up all over the city. What are they? Ghosts? Mutants? Demons? Damian doesn't know how he got here or why he is even here. He's an anthromorphic duck that must defend himself against this world. All he has on him are a box of shotgun shells and a shotgun.
