During summer holidays at Malfoy Manor, a group of Slytherin seventh-years are left unsupervised in a luxurious estate—drinking, smoking, and enjoying total freedom. But the situation quickly spirals when they’re also put in charge of two extremely chaotic children: a ruthless three-year-old Berkshire girl and a reckless five-year-old Riddle boy. Between old friendships, tension, and constant destruction, the manor turns into two weeks of pure chaos.
