Robert Ripley gives a show aboard a luxury liner at sea, starting with drawings discussing the origin of the term "fathom" and Christopher Columbus being banished from America. Film clip highlights include US curiosities such as a leaning lighthouse, a movie theater in a lead mine, a corn mosaic of the American flag, a working water pump in downtown Washington, and a beauty queen who also won a contest for making funny faces, as well as more footage from his tour of North Africa.
