Samson and the Slave Queen

During the 15th century, Philip II, King of Navarra, dies, and his two nieces, the evil Princess Malva and the virtuous Princess Isabella, struggle to determine which one will ascend the throne. The successor's name is hidden in the royal treasure chest which contains the king's will. The ambitious Malva thinks Isabella is the king's choice and engages Samson to bring the chest to her so that Garcia, her lover and the captain of the guards, can replace the document with one naming Malva queen. Isabella engages Zorro, a superb swordsman, for the same purpose after being so advised by Ramón, a poet with whom she is in love. After many contests of strength and will with Zorro, Samson finally gets the chest and takes it to the palace. He prevents Malva from receiving it, however, when he realizes that the gentle Isabella should be queen. Samson and Zorro, no longer enemies, then join forces and fight together to overthrow Garcia's guards. Isabella becomes queen and finds that the unmasked Zorro is really Ramón.
