Cristina is twenty years old. Her father was declared missing in action during the war in Angola many years before. One day in church the girl meets a man about fifty years old who tries various times, unsuccessfully, to make the sign of the cross. The man is called Cristovão. A few days later the two meet again. The man offers to help her look for her father. A relationship based on memories and confessions is formed between them. But soon they each return to their own solitude.

Vasco is a medical student in Lisbon, supported by his rich aunts, whom he had falsely told he had already graduated. In fact, he devotes himself to a bohemian life, preferring the popular fairs and pretty women, especially Alice, a seamstress from the Castelinhos quarter, which rather upsets her ambitious father, tailor Caetano, who is familiar with Vasco's debts. After failing yet another final exam, he is surprised by his aunts' announcement that they will visit him in Lisbon to see his practice.
