Ten years ago, the Collapse wreaked havoc on the world and led to the emergence of mysterious hybrids - babies born half human, half beast. Uncertain whether the hybrids are the cause or result of a virus, many fear and hunt them. After a decade of seclusion in the isolated forest, a deer-antlered boy named Gus (Christian Convery) befriends a wandering lone ranger named Jepperd (Nonso Anozie) by chance. Together, they embark on an extraordinary adventure across America in search of answers - about Gus' origins, Jepperd's past, and the true meaning of home. But their story is filled with unexpected allies and enemies, and Gus soon learns that the lush, dangerous world outside the forest is far more complicated than he imagined.
