Ali Baba and the Forty Thieves (1918)

Ali Baba, a poor Turkish wood chopper, discovers that a robbers' cave, concealed in the mountains that surround his house, opens to the magical phrase, "Open Sesame." Learning that the cave is filled with stolen treasure, he takes home as much as he can carry, but his greedy brother forces him to reveal the cave's location. After gaining admittance to the cave, Ali Baba's brother is seen by the thieves and killed. Meanwhile, Ali Baba falls in love with Morgianna, a slave girl forced to dance in the local inn, and by securing her freedom, he wins her love and loyalty. The leader of the band of robbers suspects that Ali Baba knows the secret of the treasure cave, and in the guise of an oil merchant, he visits Ali Baba with his forty thieves concealed in oil jars. When Morgianna discovers the robbers, she fills the jars with boiling oil, thereby killing them all. Ali Baba defeats the robber chief in combat and then marries his beautiful Morgianna.
