The Wasteland Giant is a post-apocalyptic drama set fifty years after the Great Drought wiped out human newborns. Silent drifter Kane accidentally discovers Luna, the world’s first infant born with eco-restoration powers created by his scientist sister Lena, who was imprisoned by the tyrant Chancellor of the White Tower. Luna’s giant transformation drains her life force, and the Tower hunts her to steal her vitality for the ruler’s failing genes. Kane embarks on a desperate road trip to protect the child, forging a tender father-daughter bond. With allies’ help, they defeat the tyrant, free Lena, and build an oasis town where Luna uses gentle seed power to revitalize the barren wasteland, finding peace after endless pursuit and sacrifice.
