The hometown of nine-year-old Javi and his brother Juan is a rural farming village in the early 1960s. Their father, they are told, accidentally killed himself while cleaning his gun, and the room where the death occurred has been declared off limits to the boys. Juan tells his younger brother that ghostly sounds can be heard in the room, but when Javi sneaks in and hears the unearthly moans, it's really the sound of their mother making love with their uncle Tio. Javi's friend Carlos has also suffered the loss of a parent, his mother, who committed suicide. Javi and Carlos sneak into a haunted house, also rumoured to be a site where spectral sounds can be heard, and they overhear something in the basement. His adventures inspire Javi to question the deaths of his father and Carlos' mother, leading to a revelation.
