13-year-old Pauline, called Pik, has lived with her grandmother Wischonka since her mother died. Pik has never met her father. Her grandmother runs a boarding kennel that is on the verge of insolvency because many customers have handed in their animals at the wrong address. Pik wants to help her grandmother and tries to raise money at Cologne airport by performing a song. But she is taken away by the airport police. Although she manages to escape from the police at first, she accidentally observes how the corrupt policeman Kowatsch and a customs officer take away seized drugs. Kowatsch realizes that he has been observed, but is unable to catch Pik.
