In the prologue an Egyptian Princess and the Prince Hassan are lovers. Nebo, the son of a sheik abducts the Princess and carries her out on the desert. She is rescued, but the Prince is killed. The son of a sheik has kicked over the sacred idol, which means that all shall die. All lie down in death. Centuries pass and the spirit of the Prince has become reincarnated in an American. The spirit of the Princess has also become a part of a young American girl, with whom the Prince is in love. The girl, her parents and lover all take a trip to Egypt to see the sights. As the old guide is showing them around the sacred temple a feeling of familiarity comes over the two as they look over the different objects. They are shown the casket of the Princess who has been dead over 3,000 years. The boy picks up a vial lying nearby and curiously opening it a puff of smoke rises and the Princess conies to life. With a surprised gasp she looks around her and sees the spirit of her dead lover before her. They are comparing notes when he notices another bottle and is opening it. She tries to hold him back, but too late. The son of a sheik comes to life. The girl and her parents take refuge in flight and are pursued by the son of the sheik. He is unable to catch them and returns. He confronts Hassan and Fatima and tells them that although the Prince killed him many centuries before, he will not get even. The two elude him however, and get outside, where they grab a couple of camels and escape in the desert. The villain still pursues them, and the only thing he can find to chase them with is a decrepit old camel. He mounts the “water wagon” and starts out, assisted by natives pushing and pulling the ship of the desert along. They have quite a chase, but the speedy mounts of the two lovers, whose love has endured through the centuries, take them to safety, and as the story ends they are congratulating themselves over the second defeat of that dog, the “son of a sheik.”
