About eight years after a zombie apocalypse, R, a zombie, spends his days wandering around an airport which is now filled with hordes of his fellow undead, including his best friend M. R and M achieve rudimentary communication with grunts and moans and occasional near-words. As a zombie, R constantly craves human flesh, especially brains, as he is able to "feel alive" through the victims' memories he experiences when he eats them.
