David is a young sculptor who accepts a friend's invitation to go on a summer trip. When he arrives and finds more people there, all men excessively comfortable with their bodies, he feels ambushed. David is forced to spend a weekend with strangers with whom he has nothing in common.

On a family trip, Germán, a modest middle-aged father, begins to hear a whistling sound that no one else can hear. The sound heralds the arrival of a creature, El Silbón, and awakens in him a wild impulse and a new desire: to be penetrated.
