Tom Newman, a hydro-electrical engineer, arrives in Africa with his family to help build a dam. His daughter, Jessica, isn't getting along with her stepmother, Amy, because she is not happy about her parents divorce. The next morning, Amy, Jessica and her brother David go on a game drive with Brian, a ranger, while Tom goes to the dam. While driving off-road, David asks the ranger to stop the jeep because he has to defecate. Brian grabs his rifle and escorts David to a nearby tree. They encounter two lionesses, backed by a lion behind them. One lioness attacks and David runs back to the car, where Brian sacrifices himself to save the others. The keys lost, Amy, Jessica, and David are trapped in the car and stalked by the lions, who devour Brian. Back at the lodge, Tom is informed of his family's disappearance, and attempts to contact Crawford, a professional hunter and guide, at the suggestion of the park rangers. Crawford refuses to help him, as he is a big five hunt guide, not a leader of search parties. The next day, after not being able to accompany the rangers in the air, Tom goes to see Crawford, and manages to hire his services at the latter's own price. Back in the car, David spots Brian's keys, and Amy retrieves them, only to wreck the truck when she drives the wrong way. Crawford and Tom look for signs of them while checking in on the rangers trail periodically, but the rain the previous night has washed away any tracks. When the rangers fly by without noticing them, Jessica gets out and tries to draw their attention. She fails and, along with Amy, is attacked by one lioness, which is killed by two native hunters.
