The imaginative Cleo feels a very special kind of affinity for her home town of Berlin. But her deepest desire is to be able to turn back time – with the aid of a magic clock which was stolen during a robbery in the 1920s and has been missing ever since. She hopes that the clock might help her undo the death of her parents. One day, she meets the adventurer Paul who is living on a houseboat and had recently bought a treasure map at an auction. Cleo is bursting with tension – might the map lead to the treasure she is dreaming of?
