Two strangers meet during a scorching summer in Rio de Janeiro. She is a designer looking for work; he has been contracted to computerize a dying publishing house. Chance brings them together in a single room, where day after day he relates to her his frequent encounters with prostitutes. She listens more than she speaks, mentally filling in the gaps in his narratives. And so they go on until the end of the summer, and nothing changes, and nothing stays the same.
