Чужой бумажник(1962)

Vacationing in a Crimean sanatorium, Nikolai Nikanorovich Staroseltsev finds someone else's wallet on the beach and gives it to the administration of the sanatorium to return it to the owner. Having become a find for bored mass-entertainers, Nikolai Nikanorovich does not stand the test of fame - and prematurely leaves the resort.
