Charlie just wants to fit in at high school. The world won't let him, because what he is forces every person around him to decide what they actually believe about humanity, personhood, and whether a life like his should exist at all. Lucy sees him as a person first, which makes their friendship the most radical act in the show. Animation corners get cut, and the pacing stumbles sometimes, but the premise never stops swinging at questions that don't have clean answers. By the time animal rights extremists show up as the actual plot, you realize they were never the real threat to Charlie. The system was.

Charlie is a fifteen-year-old stepping into high school like any other teenager, except he isn't quite human. He is a humanzee, half human and half chimpanzee, born after an eco-terrorist group freed his pregnant mother from an animal testing lab. Raised by adoptive human parents, he finally starts at a normal school, where he befriends Lucy, a clever loner who becomes his first friend. That normal life breaks apart when the Animal Liberation Alliance, now far more extreme, resurfaces as a terrorist force determined to seize Charlie and pull him into its plot. The result is a sci-fi thriller about a boy caught in the aims of people willing to go to any length.
