On 13-14 November 1990 that madness came to Aramoana, a small New Zealand seaside village. It came in the form of a lone gunman with a high-powered semi-automatic rifle. As he stalked his victims the terrified and confused residents were trapped in the village for 24 hours while a handful of under-resourced and underarmed local policeman risked their lives trying to find him and save the survivors. By dawn 13 people lay dead. This is a true story.
