Imagine on a sunny day during your holiday you went out to the outskirts of the city with your friends because there was only place which was big enough to play football. With a wrong kick your friend kicked the ball out of the field and it landed in a ditch. You set out to fetch it. When you reached the ball you glanced a bunker carved into the soil. You didn't care anymore with the ball just entered the place. Inside you found old gadgets and weapons. It rose your interest soo much you started to examine them unaware of the closing door.
