Sylvia, living with her father, a botanist in the African jungle, has a love for and develops a strange power over wild animals. When Phillip Harding, an American hunter, and his son George are about to shoot a wild animal, Sylvia prevents it. George, having fallen in love with Sylvia, promises her that he will not shoot her jungle pets. Sylvia’s father is taken suddenly ill and dies, leaving her penniless and friendless, but for her faithful servant Boto, and the beasts of the jungle. Several years pass and the theatrical sensation of the hour is a beautiful trainer of leopards, who is none other than Sylvia. She is annoyed by an admirer from whom she protects herself by releasing one of her pet pumas lying behind a curtain. Boto, her servant, becomes ill and en route home is taken into the automobile of George Harding, who has lost all trace of Sylvia. Boto is later the medium of bringing Harding and beautiful Sylvia together again, and then love plays its part.
