What makes us good or evil? It's a simple but deeply unsettling question. One that scientists are now starting to answer. Horizon meets the researchers who have studied some of the most terrifying people behind bars - psychopathic killers. But there was a shock in store for one of these scientists, Professor Jim Fallon, when he discovered that he had the profile of a psychopath. And the reason he didn't turn out to be a killer holds important lessons for all of us. We meet the scientist who believes he has found the moral molecule and the man who is using this new understanding to rewrite our ideas of crime and punishment.
In this first episode, Kate travels to south west Nepal in search of the country's last community of nomads, the Raute people. Almost all of the Raute population has already settled in Nepal and India - just one group of 140 people remain living as nomads. These hunter-gatherers still move camp every few weeks through the steeply wooded hills and mountains in one of the poorest countries on the planet. Life for this last Raute group is increasingly tough, as they face pressure to settle from Nepal's government and hostility from the farmers on whose land they camp.
