Banev finds himself in the middle of strange events linked to slimies or four-eyes - strange leper people suffering from disfiguring "yellow leprosy" manifesting itself as yellow circles around the eyes. These slimies live in a former leper colony. The town's adult population is terrified by their existence, considering them to be the cause of all the bad and odd things in the town. Nevertheless, the town's teenagers simply adore slimies.
