Synopsis

Eva seems to live the perfect life – she has a loving family, a cosy detached home, schoolwork that never overwhelms her, and she gets along well enough with her classmates. But when her mother is sent on an unexpected business trip, and her father spends less and less time at home while behaving ever more strangely, the girl begins to feel abandoned in the empty house. Eva hopes to find comfort in Loona, an exchange student arriving from Germany. At first, everything unfolds as expected, but soon the lively, boundaries pushing Loona decides to join a challenge app that is making the rounds in their class. The rule of the game is simple: anyone who accepts a challenge must complete a nerve-racking task within twenty-four hours. Eva has no intentions joining in – until her own house appears as the next challenge location.
