With a real treasure map in hand you walk along the Willemsbrug, you go on a flag hunt and in the market you learn to speak Rotterdam and what actually happened in the White House? Did you find the next point? Then you can scan the QR code on the map with your mobile phone! Through a film, a Storyteller together with actors from Rotterdam tells you a beautiful story about the place where you are and gives you an exciting mission in search of the next point.
