Historias Breves II: ¡Ratas! (1996)

A new neighbor arrives at the building with a strange suitcase. He doesn't receive visitors or talk to anyone, but a light flashes under his door. Only Lila knows his secret: she spies on him from her window and every night they share the ritual. The neighbors are scared: mysterious noises invade the building. You have to call the fumigator.
