The happily married judge Susanne has been carrying a secret with her for many years. As a 17-year-old, she released her baby for adoption. But a letter now confronts them with the past: Paolo, the Italian father of her girl, has died and has inherited his house in Tuscany to the unknown daughter. Despite better knowledge, Susanne sets out in search of her lost daughter - endangering the happiness of two families.

Oliver, a single father from Berlin, and Johanna, also a single parent but from Bavaria, meet and fall in love while on vacation. The widowed teacher and the divorced mother of two soon no longer want to settle for a long-distance relationship. Without further ado, Oliver packs his things and moves with his daughter Holly to the Bavarian province, where Johanna runs a nursery. However, everyday life in a large family thrown together presents everyone involved with unexpected difficulties. Holly is still grieving for her mother and is estranged from Johanna. Her daughter Lisa, who is the same age, is suffering from school problems that are bigger than her mother suspects. And on top of all the family chaos, the heating in the nursery breaks down, jeopardizing Johanna's livelihood.
