Captain Vincent is in command of an out-post in Arabia. Mr. Calvin, a naturalist, on his way to the interior, to collect fauna, or flora, presents a letter of introduction, as he wishes to leave his daughter who accompanies him, at this post, and to await letters of importance. While there are soldiers in the post, the servants are natives. Carol is oppressed by their silent ways, and ever-present watchfulness, but the young captain assures her that she will become used to it in time. As the days pass, the young people become more interested in each other. One day one of the servants steals a razor from the Captain who orders him whipped and in revenge the native conspires to kidnap Carol and sell her as a slave to a traveling band of Arabs. The letters arriving, the naturalist, escorted by the Captain, starts for the interior. This pleases the Arab as he will now be able to carry out his plans. He sends one of his tribe to the interior to get an elephant that he may get the girl through the jungle. Carol, in spite of warning, leaves the post and the Arab follows her and lifting her to a horse, rides away with her. The other native aids him. Lieutenant Dagwell, learning of the abduction, hastens in search of her father and the Captain to tell them of the girl’s fate. In the meantime, the wandering tribe refuses to send back the elephant to their leader as they are terrorized by a man-eating lion in the neighborhood. When the Arab gets the girl to the hut appointed as the meeting place, he does not find the elephant. He is afraid to lose time, so leaving the girl pinioned in the hut, he starts away to find the elephant. He is caught by the lion and killed. A night of horror follows, in which the hunting party struggle through the jungle hoping to find the girl, while she, a prey to terror, is menaced by the animals who try to get in the hut. Just at daybreak the hunters come upon the hut, and the shot of the Captain kills the lion, who has at last broken the door and is springing within. So all ends happily.
