The woman who appears distraught and completely soaked at a Stuttgart police station on a rainy night shows no trace of having once been a much-admired "it girl." Pony Hübner reports her SUV stolen. The terrible twist: her two children, Hugo and Penelope, were in the car. The police find the vehicle in the Neckar River, but not quickly enough; Penelope is recovered only to be pronounced dead. Hugo, however, has vanished, as has the car thief. The Hübners are wealthy, and detectives Thorsten Lannert and Sebastian Bootz consider kidnapping the most likely scenario. Especially since Pony Hübner claims she has felt followed for several weeks, a concern her husband apparently dismissed as paranoia. The relationship between Pony Hübner and her husband Stefan seems strained, perhaps even broken, and even their shared anxiety over Hugo doesn't bring them closer together.
