It's 2 in the morning. You're walking home slightly tipsy from the Imperial Union, when all of a sudden.

Darkness

You can barely breathe as the bag goes over your head, and you are tossed into what is presumably the backseat of a car. Hours pass. It's impossible to know exactly how many. The next thing you know, you are out of the car and bound to a chair, before being blinded by the piercing rays of the morning sun. As the car speeds away, your eyes adjust to your surroundings. You are sat dead centre of a junction. Any cars that are coming may not have enough time to see you. Next to you is a Nokia Brick, a compass, and a map.

Quickly you look around at your surroundings. Next to you is a cylindical bollard with a red reflector band at the top.

France

But that's not enough info. You glance to your left and spot a sign for a D road.
