 A boy named Volka discovers an ancient vessel on the bottom of a river. When he opens it, a genie emerges from there. He calls himself Hassan Abdurrahman ibn Khottab, or in Russian style Khottabych. Grateful Khottabych is ready to fulfill any of Volka s wishes. But it appears that Volka should use the powers of the genie carefully, for they can have undesirable results.
