Miss Jenny Leslie, a wealthy American girl, Blake, an American engineer, and Winthrop, an English gentleman, are the sole survivors of a vessel wrecked off the southern coast of Africa. These three are absolutely dependent upon each other in this strange country in which they find themselves, a land uninhabited save by the wild beasts, and are compelled to resort to the most primitive methods in order to provide themselves with the bare necessities of life. The American, Blake, a rough and uncouth individual, whom the wealthy on board the vessel had shunned, now takes the lead while the Englishman proves helpless under the trying circumstances and finds himself obliged to follow the dictates of the stronger character. The necessity for strength and courage brings out the fine character of the girl, and, despite the fact that she had been waited upon all her life, manages to adapt herself to the predicament in which they are placed. While at first despising the engineer, she grows to admire his strength of purpose and power to command, and a romance develops between these two.
