After seven years of a happy long-distance relationship, Munich gallery owner Katharina and Murnau hotelier Peter finally want to move in together. However, this decision does not seem to be under a good star: Due to water damage, they are unable to move into their new house and are forced to stay with Peter's daughter Verena and her children. When Verena has to travel to visit her husband who has died in an accident in Chile, Peter and Katharina are left with the task of looking after the children.
