Micha Oberländer and his new colleague Mara Eisler are just starting to warm up to each other when they are called to the local fairgrounds, where the 19-year-old Lorena has been found stabbed to death in a gondola of the Ferris wheel. The fairground workers claim not to have known the deceased and no one heard or saw anything. But through Lorena's school, the investigators learn that Lorena had been living with the troupe since she illegally immigrated from Armenia two years ago. When Oberländer and Eisler find out that Lorena was pregnant, but her boyfriend Gino is not the father of the child, the dysfunctional community's web of lies slowly unravels and everyone seems to have a motive for murder. Who is the father of her child? And what happened on the recent school trip, where all the threads seem to come together? Oberländer and Eisler must work together to decipher the murky fairground world with its very own rules in order to prevent another murder.
