The Diamond Arm

In a southern town, a gang of currency speculators is led by the Chief and his assistant, the Count (known as Gena Kozodoyev in everyday life). Semyon Semenovich Gorbunkov, a humble Soviet employee and devoted family man, embarks on a foreign cruise aboard a ship, where the Count is also traveling. The Count is supposed to pick up diamonds in an Eastern city and carry them in a cast on his hand. However, due to a misunderstanding, Semyon Semenovich falls at the designated location instead of the criminal, and the precious cast is placed on his hand.
