Incredibly, the "Secret Seven" has lost one of its members - George is out of the game due to a misunderstanding. And just then a new business is being planned, the thread to which George gave the guys. Had he really gotten on the trail of criminals while doing Peter's task to practice his surveillance skills? And can this seemingly hopeless investigation become a real adventure?
