Once upon a time, there were two neighboring countries that did not get along. They bickered over trivial things day in and day out. Finally, they went to war over the issue of cleaning up dog feces. God intervened in a hurry and said to the chiefs of the two countries. Country A gives its most beautiful girl to Country B as a bride and Country B gives its wisest young man to Country A as a bridegroom. Then, the princess of country A, Saara, happens to meet a young man from country B...!

International Rescue soon receive a call from a yeti on Mount Everest pleading for rescue, with Penelope sent to investigate. All the while, a series of robberies plagues British Stately Homes.
