Plot
Recently widowed Dr. Nate Samuels and his daughters, Meredith and Norah, arrive at the Mopani Reserve in South Africa for a vacation. Nate reunites with his old friend, Martin Battles, a biologist and Mopani manager, who introduced Nate and his wife. Martin takes Nate and the girls to the village where Nate's wife grew up. Nate confides in Martin his guilt over being distant following his and his wife's separation, after which she developed terminal cancer. The trip is to reconnect with his daughters.
The next day, Martin and the family tour the reserve's restricted areas. Martin shows the trio a local lion pride that he helped raise, and notices that one of them is injured. At a nearby Tsonga community, Martin discovers that most of the population has been killed. Suspecting that a rogue lion is responsible, Martin rushes back to report the finding. Nate encounters an injured Tsonga man on the road, but is unable to save him. Martin is attacked by the rogue male lion; it then ambushes Nate, who takes cover in the car. Meredith speeds away but crashes into a tree, stranding them.
Martin radios Nate on a walkie-talkie, warning him to stay away, as the lion may be using Martin as bait to lure the others out. As the radio is out of range to contact help, Nate assembles a tranquilizer rifle, hoping to subdue the lion long enough to recover Martin and trek back to civilization. The lion attacks, and Meredith takes advantage of the distraction to save Martin. Norah stabs the lion with a tranquilizer dart after it knocks the gun from Nate's hands, causing the lion to retreat. Meredith brings Martin back to the car, and Nate treats his wound.
As night falls, a now-recovering Martin speculates that the lion went rogue after poachers killed its pride. Soon after, the poachers arrive and initially agree to transport the group to the village in exchange for payment, but tensions rise after they spot Martin, an avid anti-poacher, inside the car. The lion attacks and scatters the poachers, killing most of them. Nate maneuvers his way past the lion and finds the poachers' truck keys. Back in the car, Martin holds the lion off long enough to allow the sisters to escape, though Meredith sustains a deep laceration to her side. The car falls into a ravine and Martin sacrifices himself by setting off an explosion from the leaking gasoline, severely burning the lion. Nate starts the truck and races away with Meredith and Norah, but has to stop before they run out of fuel. They leave the truck and walk to an abandoned schoolhouse nearby, which the poachers used as their base.
Nate treats Meredith's wound and forages for water. The lion appears and stalks the girls, but Nate returns and scares it off. Locking his daughters inside a room, he promises to return after subduing the lion. After provoking the lion into chasing him, Nate lures it to the local lion pride. The rogue lion overtakes and mauls Nate, nearly killing him, but the lion pride's males, Kuda and Kawe, intervene and kill the rogue. A Mopani worker named Banji arrives and saves Nate as he loses consciousness.
Awakening in a hospital, a recovering Nate tells his daughters he loves them. Sometime later, the three return to the reserve, this time as a united family, and recreate the photo Nate's late wife took of herself next to her favorite tree.
