A middle-class father Ricardo (Castro) takes his two daughters to their lakeside family house in southern Chile.Out on a yacht one day, they see three young local fishermen waving at them from another boat which is rapidly taking on water. Ricardo refuses to go and help, arguing they look suspicious, much to his older daughter’s exasperation. His prejudices will have dramatic consequences.

Raquel has been the live-in housekeeper for a kind, reasonably wealthy family for half her life, and the joyless repetition of the job has begun to take its toll. Increasingly dependent on painkillers, Raquel resorts to pranks and childish avoidance to antagonize the family’s college-age daughter and a procession of new servants, all in the hopes of protecting her precarious power within the home. Her antics successfully push everyone away, until new maid Lucy actually pushes back.
