He is already preparing to wallow on the beach, bask in the gentle sea and communicate with pretty girls, but instead falls into such a deadly whirlpool of events that the worst nightmare will seem like a funny Disney studio craft. Two forces will collide on the Yangel plateau - an ancient powerful evil and a human mind armed with modern technology.
