This isn’t how Karin, Gerhard, and Philippa imagined their retirement: instead of enjoying their free time they feel bored, useless, and…old! In the search for a new perspective, they become “Granny-Nannies" and each gets a family with children to take care of. But instead of harmony and gratitude, they are soon confronted with overprotective parents, hyperactive children, and all sorts of family problems. Although facing turbulent times, they will find out that it is never too late to build a happy retirement!
