A whole community of vegetarian zombies rests under the cemetery of Saint-Onitague. Xavier, who died at the age of ten, is adapting very well to this new life: he no longer goes to school and he no longer needs to wash himself. The young boy is worried, however, for his younger brother, the sole survivor of the car accident which also killed his parents. To make sure that this one is okay, Xavier breaks the first zombie law which forbids walking among the living. A series of encounters reveals the secret that threatens the survival of the village's underground community.
