Tony, a trapeze artist, gets a job at a small circus. When a tempest takes away the tent, Tony stays for the love of the beautiful Belmira who could be a rider… if they hadn’t sold the horse. They play at open-air, sleep under the stars, scrimp and save every penny, and soon there’s a new tent to be bought on credit. But Belmira is not happy, she dreams of a real home, while Tony is fascinated by the circus. And the gloomy days are back.

Having abandoned his family due to religious differences, Dr Silveira moves to Coimbra, where he dedicates himself to his patients, and rejecting any attempts at reconciliation. But, when a terrible accident happens to his son, he must seek a resolution to the debate between faith and science.

Luisa and Manuel begin the existence of married, having only their dream and hope. He judges himself a Tarzan in the jungle of life, able to face all the threats, next to his companion.

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. The deaf musician Sparrow watches over her, in his despaired love and long-held wish of becoming a sea captain. There is a dispute down the piers, there is a crime that might be just an accident, there is a bad conscience that turns sour, there is a boat full of poor wretches like a rocking lullaby, a baby that passes from arms to arms, a clumsy beggar that finds some work, a courthouse of tramps... From this expressionist account that has unexpected comical moments, the censors from Salazar's regime cut away 20 minutes that were never to be found again.
