Freddy and his wife Juliana leave the comfort zone of Constance and move to Berlin. With Grandpa Fritz in tow, the Kleemanns move in with Grandma Regina. Unlike his sister Zoe, little Niko is happy to be living with his grandparents. While Freddy and his trusted colleague Lara finally want to implement their own concept as daycare center managers, Juliana sees an unexpected stop sign in her career as a doctor: she is unplanned pregnant! Now a difficult life decision has to be made: a third child does not fit into the current family and couple concept of two full-time professionals.
