A Filha de Iemanjá(1981)

One day, a fishing couple finds a crate on the seashore containing a child. They decide to raise the girl, convinced that she is the daughter of Iemanjá, judging by her origins. Meanwhile, Teixeirinha, a famous singer and composer, is experiencing a period of profound isolation due to the death of his wife. Because he composed a beautiful song in homage to the goddess of the waters, Iemanjá, she takes pity on him, sending her daughter to ease his pain and encourage him to compose again for the joy of his people. Amidst encounters and partings, the ending is surprising, as love doesn't always conquer pain. Or does it?
