Bi-Mezulot Yam ("In the Depths of the Sea") revives a terrible episode of the exodus of the Jews from Spain (1492). The refugees embarked on pirate vessels, where they were exploited pitilessly. The cupidity of the corsairs is insatiable. After despoiling the Jews of all they own, they sell them as slaves or cast them into the water. This is the lot that threatens to overtake a group of exiles on a certain ship. But the captain falls in love with the daughter of a Rabbi, a maiden of rare beauty. To rescue her companions, she pretends to yield to the solicitations of the captain, who promises to land the passengers safe and sound on the coast. He keeps his word, but the girl and her mother must stay with him.
