Eunice, a beautiful slave girl, falls into the hands of a band of outlaws, and is taken to their cave, in which they store the jewels and precious wares, the result of their plundering. In the meantime, an aged woman happens to catch sight of Eunice and the outlaws on their way, and, recognizing the girl, rushes to inform Ben Ali, the master, of his slave's predicament. Ben Ali hurries to the entrance of the cave, and secretly overhears the password, by means of which he soon rescues Eunice. Later he informs the chief magistrate, who summons his soldiers, and, taking the outlaws by surprise, inflicts a terrible punishment upon them. He then publicly thanks Ben Ali and Eunice, and generously rewards them with a large quantity of the treasure.
