In the drought areas of Northeastern of Brazil, groups of migrants move trying to find better place to live, at least with water. Some of them go to Recife, to get a vessel to Santos expecting to have a better life in the Southern. In the poor area of Recife, an old washerwoman launders clothes to survive and support her family. Her husband Zé Luis, a former sailor, is crazy due to a hit of the boom of a mast on his head. Her older son Raimundo works in a grocery and selling mangoes on the street, trying to save money to move to the Southeastern with his girl-friend Aurora. Her daughter wants to be a prostitute to have a better quality of life. Her younger son is seriously sick.
Silke just loves water. She loves to bathe and to swim like a fish. As a matter of fact, she only feels fit and well when she is in the water. This is because she has an eczema which makes her skin itch. Her father and mother are worried about her and take her to the doctor. But strange things happen, and a dolphin, a dog and an old, long ago deceased pirate-grandfather emerges in the story. This is because Silk is not like other children - especially not when she hears the song from the sea.
