A very valuable piece of jewelry made by Sultan Suleiman the Magnificent for Hürrem Sultan is put up for sale. At the end of the auction, the necklace is sold to an Englishman named Morgan. A company called Lloyds Insurance has insured the necklace. The necklace will remain in Istanbul for a while longer before being transported to London by ship. Meanwhile, a theft gang called the Squirrel Gang, whose name appears on the Interpol list, will also be traveling on the ship. However, the Squirrel Gang is not the only organization after the necklace.
