Karin, Gerhard and Filippa have retired. However, instead of enjoying their free time, they feel old and useless. So they decided to look for a job. Soon the world is spreading about a new initiative - "grandma nanny". They want to help busy families with looking after their children and keep themselves busy. However, it quickly turns out that hyperactive children, overprotective parents and family problems are not what they expected, and it is never too late for a happy retirement!
