Dan is on a trip with his family because his mom is in a baking contest and they travel to London for the finals. But while dan's mom was getting stuff ready for the challenge in 3 days Dan goes exploring and bumps into someone. When they see each other they were shocked. And then the look alike asks dan to switch places for 3 days and they will switch back the night before the contest. But trouble happens and dan and his look alike must work together to stop it. This my own story and my own idea on this story.
