The plot of the movie unfolds through the testimonials of three young sisters: Uring (Pia Peron), Luray (Sachi Sanders), and Elya (Jean Andrews), who recount the grisly sexual molestation they experienced from their adoptive father Timo (Michael de Mesa). The title was taken from the sisters` work as stone tillers in a quarry where most residents earn their living. Apart from being an alcoholic and gambler, Timo is a sex pervert.
