With his father (David Oyelowo) always critical of his fanciful nature, Gunner (Lonnie Chavis) turns to his kind-hearted mother (Rosario Dawson) for support. However, when his mother's health declines in the face of a terminal illness, Gunner strives to reconcile with his father while seeking alternative healing methods. It is in his science fiction books that Gunner encounters tales of the Water Man, and with the help of his feisty friend Jo (Amiah Miller), Gunner embarks on a mission to an unusual forest to seek the Water Man's help. Directed by first-time filmmaker David Oyelowo.
