Crying children, changing diapers, baby food - everything around Jan seems to revolve around having children. Not only is his best friend Theo a new father, but his sister-in-law Marion's children also keep the successful engineer on his toes. So it's all the better that Jan's marriage to Hanna is a child-free zone. Until now - because Hanna's family plans are becoming more and more concrete... When she brings up her desire to have children one evening, a heated argument develops that ends in a compromise: To test whether the couple is even ready to take responsibility for a child, they first want to look after a dog for a few weeks. If that goes well, they can start thinking about having a baby. A short time later, bulldog Lucky moves in with them and causes a huge stir in the couple's lives...

For Johannes and Lydia Klare, their faith in God comes first. Together they lead a small community in Stuttgart, successfully. People listen to them, they are becoming more and more close to them. There are even plans to make the donor-funded community much bigger by the generous contributions of Volker. First of all, the couple have quite different, more urgent points to take care of. When one day they watch the homeless street-boy Simon drifting back and forth in drug-related crises, they take him in for a short while. Together they want to help him again on the right path. But it is not just the drugs that are causing conflicts. Simon's homosexuality also presents the two with great challenge, since it is not so easy to unite with their faith.
