Following the sudden suicide of his father, sixteen-year-old Paul seeks refuge and comfort by unexpectedly showing up at the pristine, suburban home of his wealthy relatives. While his distant uncle Stefan and cousin Robert are mostly indifferent to his grief, Paul’s vulnerable presence deeply disrupts his elegant, domineering aunt, Anna. Sensing the intense friction and emotional isolation within the household, Anna begins to use her nephew as an emotional instrument to wound her cold husband. The psychological boundary-pushing quickly spirals into a highly toxic, manipulative incestuous affair between the desperate teenage boy and his older aunt. As their secretive, taboo relationship intensifies during games of pingpong in the garden, it systematically strips away the family's carefully manicured facade, leading to a volatile and destructive emotional collapse.
