Wolf King is Netflix's CGI adaptation of the Wereworld books by British author Curtis Jobling. It is set in a fantasy land called Lyssia, where noble houses have the power to transform into half-animal hybrids. A farmboy named Drew Ferran (Cel Spellman) learns that he is the last of the wolflords, and Lyssia's only hope of overthrowing the usurper king, the lionlord Leopold (Ralph Ineson).
