Hunt for the Cossack Gold

In ancient times, the Ukrainian hetman sent treasures with his son to the British bank, hoping that Ukraine would be free and then the gold would help the people thrive. Hetman also told his son the secret code to access the gold in the bank. Nowadays KGB agents and foreign spies are following the hetman's descendant Ivan Polubotko, a phlegmatic and dimwitted man, hoping to acquire treasures with his help.
