Revolving around an isolated and ambiguous mansion: It is inhabited by six eccentric characters: Paul, a guardian, who patrols the property with his German Sheppard; Camilo, an impotent alcoholic pilot; a monk, with a passion for books; Cristobal, a black servant who does the daily chores; the Machiche, a mature voluptuous woman who keeps the men in the house under her control; and Graciliano "Don Graci", the pampered and corrupt owner of the house. A young model Adriana, who is working on a TV commercial that is filmed nearby has a tantrum and runs away on her bicycle. She arrives at the mansion of Araucaima and asks permission to use the bathroom. The owner invites her for dinner as the chain of her bicycle is broken and is already late. She starts to affect the group's long-held equilibrium until cracks, and dissensions begin to crumble the entire social structure.
