VAP and the Black Watch

After eight years of marriage and three children, VAP has a new invention. An American banker becomes interested in purchasing it. VAP plans a belated honeymoon in the Bahamas but Chip discovers it is actually a business meeting with the banker. The children are left with their grandparents and the youngest, Mi.Psy, and Neri, their faithful dog, are kidnapped by robbers. VAP doesn't understand what is happening, whizzes back home on the disused WebLine, finds the pair, then rushes back to the Bahamas to discover Chip is having problems with the banker's assistant, who is trying to steal VAP's designs. VAP and Chip return home to find that Mi.Psy and Neri have not only trapped the criminals in a secret room in the castle but also found the von Strenge treasure.
