A continuation of the adventures of a Moscow auditor who was pulled from our time into 1971. Settling in as Pavel Ivlev, a schoolboy, he develops frantic activity. He needs to help his family and friends, to think about his career in the USSR, to prepare for military service. He must find the villain who killed his dog, and, of course, try to locate the super prize—two hundred thousand Soviet rubles hidden somewhere by a thieving base-hulk.
