Peacefully slumbering Jerry is disturbed, first by a cop and a nurse girl wheeling a baby, and then by a colored cop with a negro woman, who also has a baby. Incensed, Jerry determines to have his revenge and changes the babies. Jerry then comes upon a sergeant. He conducts him back to the park bench. Upon the appearance of the sergeant the two cops rush off. The negro woman exits with the white baby, while the white nurse leaves with the colored baby. Consternation reigns when the parents discover the substitution. The black cop and the white cop catch a glimpse of Jerry in the background. They soon catch him. A fight ensues. Two white cops rush up and in the general mix-up Jerry makes his getaway. He soon comes upon an aeroplane, gets into the cab and soars upward. Jerry arrives over an island inhabited by cannibals, who have all the modern improvements. The cannibals discover Jerry and notify their chief by telephone. Acting under the instructions of the chief, who arrives upon the scene in his racing car, the cannibals fire and the machine falls to earth. Jerry is carried to a large kettle and forced to witness a cannibal dance. He knocks the chief into the kettle and dashes off. In his mad dash for life Jerry comes to the chief's tent. Darting inside he comes upon a beautiful princess, whom the chief is holding captive. She hides him in a suit of armor. The chief enters the tent. While he is questioning the princess, Jerry prods him with a spear. The chief angrily accuses one of his men. Jerry then prods the other man and causes a general fight. Taking advantage of the confusion, Jerry escapes with the princess. The chief's racer is standing outside the tent. Jerry helps the princess into the car and drives safely away just as the chief and his men run out of the tent.
