Twins Max and Anni have had the worst birthday ever. Max has missed a vital goal in the football Cup Final and Anni has fallen out with her best friend. Feeling thoroughly miserable, Max and Anni sneak downstairs at midnight and light the candles on their untouched birthday cake and, as they blow them out, they make a wish . . . to redo the day!

When they wake up, their wish has come true! And this time Max and Anni aren't going to mess things up. But little do they realize that they are going to have to relive their birthday again . . . and again . . . and again.
