In this animated adventure, Wadams, a young monkey, is abducted by human scientists. In their laboratory, Wadams learns about the theory of evolution. Not understanding the concept, he eagerly awaits his chance to become a human being, until his father dies as a result of the humans' experiments. Wadams vows to stop evolution. With his girlfriend, his science teacher, and a team of underground French revolutionary monkeys at his side, Wadams must convince the conservative monkeys of his village that evolution is real, and figure out a way to prevent them all from becoming human, before it's too late.
