A boy raised by monkeys returns to the tribe that tried to kill him as an infant. Instead of revenge, he finds a girl worth saving, and the show lets their relationship breathe across the entire series without rushing or cynicism. This is a 1971 love story that believes in second chances and quiet moments in a prehistoric world, which is exactly why it still matters to anyone tired of anime that screams for your attention.
In a prehistoric age when people live alongside dinosaurs, Ryuu is born with white skin, unlike the rest of his tribe. The elders leave the infant as an offering to a fearsome tyrannosaur, but an ape takes him in and raises him as her own child. His real mother abandons the tribe to search for him. Years later, Ryuu meets Ran, a girl who was sold to the tribe he came from. Angry to find him alive, the tribe tries once more to sacrifice him, this time by setting him on fire. Before they can, the tyrannosaur slaughters them, killing Ryuu's adoptive mother as well. Ryuu then sets off with Ran on a long journey to find his mother and Ran's younger brother Don, who was separated from her when they were small. The series is a prehistoric adventure with a thread of romance.
