The Pearl Necklace(1965)

For nine-year-old Saša, the end of the Second World War is an adventure in which he and young neighbour friend Mařenka compete over who will spot the first Soviet soldier. But the boy causes problems when he lets two German snipers enter a house in which many families are seeking shelter. Fortunately, the inquisitive Saša also comes to the aid of Soviet soldier Váňa, whom one of the neighbours is accusing of stealing a pearl necklace.
