Exposed to the romantic schemes devised by Álvaro, Juvenal vigorously defends the exploited workers and is reunited with Elisabeth, the great love of his youth. Wounded while taking part in a popular demonstration that is violently suppressed by the police, he is sentenced to exile on the island of Sal. Elisabeth decides to accompany him, announcing that she is expecting his child... eternity!
