From renowned Russian director Leonid Gaidai comes this witty farce -- based on a story he read in the newspaper -- about a criminal gang that smuggles diamonds and rare coins inside a plaster arm cast. When genial Semyon Gorbunkov (Yuri Nikulin) embarks on a getaway cruise, he becomes the unwitting pawn of the baddies, who mistake him for their cohort. After realizing their error, the crooks set out to recover their loot by any means necessary.
