Out of the Blue
On November 13th 1990, in the small New Zealand seaside town of Aramoana, local man David Gray took a high-powered automatic weapon and shot dead 13 people.
At the time, it was the worst mass murder in New Zealand's history.
As emergency services scrambled to reach Aramoana, a handful of young, under-armed local policemen risked their lives trying to find the gunman.
Terrified and confused residents were trapped in their homes for 24 hours, not knowing where David Gray was - or if they would become his next victim.
There were great feats of bravery on that terrible day - from ordinary people in the most extraordinary of situations.
Out of the Blue is a gripping and powerful story of courage and survival.
