A boy arrives - breathless and aghast - at his police station, to report the discovery of a horribly maimed body outside an isolated house in the woods. Yet there was another person in the woods that day - standing nearby, hidden within the trees, was the mysterious figure of the local misfit, Errki. The next morning a bank in the nearby town is robbed at gunpoint. The gunman takes a hostage and flees. As his plans begin to come apart he, unlike his passive hostage, rapidly loses control. Meanwhile the search for the killer has developed into a manhunt - everyone is looking for the enigmatic Errki.
