Mr. and Mrs. Harry Pearson tell their friend, the Major, that they are planning an expedition to Africa. They tell the Major that they are going to try and photograph many African rarities, including scarce animals and strange native tribes. After packing, the Pearsons travel by boat to England, where they board an Imperial Airways plane to Nairobi, in the British colony of Kenya. In Nairobi, they assemble their expedition force and head into the wild game country of the Serenageti Plains in the Tanganyika Territory. Once in the game country, the Pearsons find and shoot many different types of wild game, including lions, zebras, antelopes and cheetahs.
