Friends Nina and Franziska live in the same building on the market square in a small town in southwest Germany. In a fit of champagne-induced enthusiasm, they and four other women found the ›Nutters’ Club‹, based on the idea that there is something odd about each one of them. 
When Nina loses her handbag, she makes the fateful acquaintance of Andreas Haase. Not satisfied with the usual finder’s fee, he wants more – and Nina will need to rely on her best friend more than ever before.
