Needle in a Haystack (1953)

Mariana is a young woman from the interior of Minas Gerais who leaves for Rio de Janeiro in search of a man who seduced her and got her pregnant. But the rascal man gave her the false address, with only a photo as a reference. Staying at an uncle's house, she is faced with the difficulties of living in the big city, seeing that finding her husband in Rio is like looking for a needle in a haystack.
