A young thief faces amazing monsters to return Bagdad's deposed king to the throne.

As the Princess slumbers while awaiting the blind man whom she loves, Jaffar, the evil magician who desires her, sends his aide to lead the blind man to his palace. At the palace, the man reveals that he is Ahmad, the King of Bagdad, and relates his life story and that of his dog, the prince of thieves: After being betrayed by his vizier, who is the same treacherous Jaffar, Ahmad is imprisoned and meets Abu, the boy thief. The pair escape and flee to the city of Basra, where Ahmad falls in love with the beautiful Princess, but their romance is shattered by the shrewd Jaffar, who offers the Sultan a winged horse in exchange for his daughter. When the Princess runs away rather than marry the dreaded Jaffar, the magician eliminates his rival by blinding Ahmad and turning Abu into a dog. His story finished, Ahmad is led to the sleeping Princess by Jaffar's aide. Awakened by her lover Ahmad, the Princess is then kidnapped by Jaffar, who sails away with her after restoring Ahmad's sight and Abu's body. Ahmad and Abu follow, but their small craft is destroyed by the winds that Jaffar commands. Shipwrecked, Abu finds a bottle and releases a genie who grants him three wishes. The genie leads Abu to Ahmad, but the boy squanders his last wish by cursing Ahmad to return to Bagdad. The genie complies, and in Bagdad, Jaffar arrests Ahmad and the Princess and sentences them to death. As the two await execution, Abu is rescued by "the legendary ones" and is presented with a bow of justice. Commandeering a magic carpet, Abu flies to Bagdad just in time to rescue Ahmad and slay Jaffar with an arrow of justice.
