A young boy (Lewis MacDougall) befriends a wise tree monster (voiced by Liam Neeson) while coping with bullying and the terminal illness of his mother (Felicity Jones). He moves in with his grandmother (Sigourney Weaver) as his mom's condition deteriorates, and uses his imagination and friendship with the monster to escape reality. J.A. Bayona (The Impossible) directed this fantasy drama.
