Chris, a student, ambitious in his own way but resisting tutors, was always in trouble until, at an auction sale, he purchased an old Oriental lamp because of its odd design, not dreaming that it was possessed of magical powers which he discovered when he began polishing it. A huge slave appeared, told him the lamp was his master and that he was prepared to obey any command that its owner, Chris, might give. As a test Chris bade the slave to transform himself into another Chris. He then sent the double of himself to school, where he was made to take the thrashings intended for Chris and to serve as the butt of many jokes and experiences meant for the real Chris. When the genie finally decides that he does not relish serving as Chris' double, the real trouble and fun begins, involving Chris' father and mother, teachers, family doctor, and farcical mix-ups develop with great rapidity. The doings of "Chris and the Wonderful Lamp" in the days of the Twentieth Century rival the best of Arabian Night tales.—Moving Picture World synopsis
