In British East Africa in the early 20th century, thousands of workers are building the Uganda Railway, Africa's first railroad, and intense heat and sickness make the project a formidable task. Bob Hayward and Dr. Angus McLean lead the mission. A pair of man-eating lions are on the loose and completely disrupt the undertaking. Hayward desperately attempts to overcome the situation, but the slaughter continues.
Britain sends three big-game hunters to kill the lions, and Bob's wife also arrives. After the hunters are killed by the lions, Bob resolves to kill the lions himself. A grim battle endangers Bob and his wife, but Bob kills the lions.
