Meia-Lua used to be a sailor, but he now makes a poor living smuggling. He is a cynical man, who doesn't care for Ana or for the child they had together. He lives with the beautiful Marlene who dances in the bars. Gull spends her whole days lulling a doll in her arms, and she waits for her love that will rise from the depths of the sea.

Fiction within fiction, stories within stories, like those Chinese boxes in which there is always one inside another. Or the two margins of the same river, always being lateral.

Rui, a young musician, is writing poems for the vaudeville company.
