Noise (2007)

Graham McGahan is a cop - almost by default, he thinks. Self-centred, beset with doubt and afflicted with tinnitus, a few days before Christmas he is sent by his boss to man a police van in a suburban shopping strip, after violent murders rock the local community. McGahan starts to engage with traumatised members of the local community, as they deal with the after burn of these terrible crimes. He learns to come to grips with his role as a cop and a man. But terror has a way of finding the most vulnerable amongst us.
