The trip, which begins as a journey of healing, quickly turns into a heart-racing fight for survival when a lion, who views all humans as the enemy after surviving blood-thirsty poachers, begins stalking them.

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

“Beast” hits theatres this summer on August 19.
