Ali Baba discovers the treasure cave of robber-baron Abu Hasan, and tells his greedy brother, Kasim Baba, who is posing as a Chinese merchant and entertaining Hasan, where the cache is hidden. Zahrat, acting as a spy for Hasan, is blamed when the robber is almost caught, and Kasim is killed. Zahrat then decides to join Ali and his son, Nor-al-din, who is in love with the slave-girl, Marjanal. During a party, she kills the disguised Hasan, and his men are boiled in oil.
