Thoughtful, inventive comedy by Adam Rosenthal and Viv Ambrose. Newfangle (Russell Tovey) is one of a tribe of humans at an early, pre-verbal stage of development. Picked on by the alpha male (Hugh Bonneville), hopelessly in love, looked down on by his mother (Maureen Lipman) who prefers his brother (Gabriel Vick), Newfangle is a thinker and one day, wishing to express his thoughts out loud, he invents language. Then people start using it for things he didn't intend. Soon prehistory turns out to quite a lot like life anywhere, anytime. But funnier.
