Explorers Martin and Osa Johnson set out an an expedition that takes them to Hawaii, the little explored South Pacific regions of the Solomon Islands and the New Hebrides Islands, Australia, then through the Suez Canal, down the Nile River to Tanganyika, a safari to the Belgian Congo--where they observe a large variety of wildlife and meet up with a tribe of pygmies--and finally wind up in Uganda.
