Sometimes the rustle in the bushes actually is a monster.

Idris Elba (Fast & Furious Presents: Hobbs & Shaw, The Suicide Squad) stars in a pulse-pounding new thriller about a father and his two teenage daughters who find themselves hunted by a massive rogue lion intent on proving that the savannah has but one apex predator.

Elba plays Dr. Nate Daniels, a recently widowed husband who returns to South Africa, where he first met his wife, on a long-planned trip with their daughters to a game reserve managed by Martin Battles (Sharlto Copley, Russian Doll series, Maleficent), an old family friend and wildlife biologist. But what begins as a journey of healing jolts into a fearsome fight for survival when a lion, a survivor of blood-thirsty poachers who now sees all humans as the enemy, begins stalking them.

Iyana Halley (The Hate U Give, This is Us series) plays Daniels’ 18-year-old daughter, Meredith, and Leah Sava Jeffries (Rel series, Empire series) plays his 13-year-old, Norah.
