In the desert Ali finds the hideout of the only resistance force, the forty thieves, and he joins them and grows up as one of them. Meanwhile his betrothed, the fair daughter of Prince Kasim, is taken to Baghdad by her father to be married to the Mongol leader, Hulago Khan. Ali goes to Baghdad and captures her but soon sets her free. She learns that he is her betrothed as well as the leader of the band of thieves. Her wedding to the Khan is set for Ramadan and so Ali Baba and his band of thieves attend the celebrations parading as traders. A great fight ensues and the Khan is killed, Baghdad is freed and Ali and his princess live happily ever after.
