Unbelievable Adventures of Italians in Russia

In the hospital in Rome, Italy, an old Russian emigrant woman dies. Dying, she tells her granddaughter that she has hidden her treasures in Leningrad under the lion. Unfortunately, beside her granddaughter she was heard also by a solid doctor, 2 male nurses, an Italian mafioso and a hobbling man. After that they all fly to Russia by the same flight (of course none of them tells the others that he’s flying to Russia for the treasures). Having some adventures in the airplane because of mafiosi, they all arrive to Leningrad and begin to dig under every lion statue in the city. —wikipedia
