An unprecedented - and wholly unpredictable - action-adventure, Roar follows wildlife preservationist Hank (The Exorcist producer Noel Marshall in his sole and career-derailing turn as an actor and director), who lives harmoniously alongside a menagerie of 100+ untamed animals, including cheetahs, elephants, lions and tigers on a preservation in the African plains. When his wife and children arrive (real-life wife Tippi Hedren and step-daughter Melanie Griffith) for a visit, a long-brewing battle for dominance between the lions erupts and threatens their very lives.
