Retirees Karin, Gerhard and Philippa are not in the mood for Nordic walking and seniors' courses at the university. When Philippa, who is living life to the full as Leonie's godmother, helps the two to unexpected grandparenthood, they suddenly have two "lively" god-grandchildren to look after, a huge bouncy castle standing in the garden and Lego bricks stuck to their feet.
