Pastor Stefan Book once again has his hands full in his parish in St. Pauli: he has only just managed to talk the mentally distressed sexton Eddi out of attempting suicide when he learns that 16-year-old confirmation student Paloma and her boyfriend Winni, who is the same age, are expecting a child. As Paloma is still living with her alcoholic mother, the youth welfare office would prefer to give the baby to foster parents as soon as it is born. But Pastor Book fights to ensure that the two teenagers can take responsibility for their child despite the adverse circumstances.
