At the Melrose family's glorious house in the South of France, young Patrick has the run of the magical grounds. His father David rules with cruelty and his mother Eleanor has retreated into self medication and booze. Bravely imaginative and self-sufficient out of necessity, 9-year-old Patrick encounters the volatile lives of adults with fear. They are expecting guests for the weekend, but this afternoon is profoundly unlike other summer days, and the shocking events that precede the guests' arrival tear Patrick's world in two.
