Out of the Blue (2007)

Ordinary people find extraordinary courage in the face of madness. On 13–14 November 1990 that madness came to Aramoana, a small New Zealand seaside town, 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 for 24 hours while a handful of under-resourced and under-armed local policemen risked their lives trying to find him and save the survivors. Based on true events.
