There, in the maze of narrow streets of Old Town, shadowy neighbourhood lies. Old houses and curvy streets make dark places in the night. That's the world of Vonts, mysterious group of people, gathering in the garden of St. Jacob's church. Their activities are cloaked to outside people. All there is known about them is that they wear a yellow pin on their jackets. Yellow is their color. Žlutá je barva naše! Yellow is our color!
