(In the 12th century, the city of Derfolk is divided by a wall. On the left live the people from the south and on the right the people from the north. Both sides are hostile to each other and are not allowed to have any relations with each other. Tonight, three friends, Paul, Darek and Elvin, sneak to a secret opening at the end of the wall that separates the city. They want to get from the south side of the city to the north side of the city to the house of the Northfolt family where a ball is being held today.)
