"The Beast Boy" is a coming-of-age survival thriller with elements of Cronenberg-style body horror. Garfield "Gar" Logan is a former child star turned social media influencer who uses his green skin and shapeshifting abilities for clicks and fame. But behind the TikTok dances and the smile, Gar is terrified. He is suffering from a progressive mutation of the Sakutia Virus that killed his parents in Africa.
The transformations are becoming painful, violent, and harder to control. He isn't just turning into animals; the animals are trying to take over his mind. When a shadowy organization known as N.O.W.H.E.R.E. (led by the calculated Niles Caulder, who claims he wants to cure Gar) attempts to capture him for vivisection, Gar flees into the Pacific Northwest wilderness. He is forced to survive not by acting like a hero, but by embracing the "Red" (the primal force of nature). The film is a chase movie where Gar must learn that being a "Beast" doesn't mean losing his humanity, even as his bones break and reshape into something terrifying.
