Guy Pearce plays Munro, a lay preacher tasked with looing after a new British settlement on the coast of 1830's New Zealand. The area is riven still with tribal wars and Munro becomes involved in these by accident, during other endeavours.
While this does not pretend to be an accurate retelling of events, it does portray very much the feelings of the time. Tribes who think revenge blood is the only redemption, explorers who think they have a right to other lands, a King who seeks to rule over lands he's never even seen, and the power of the passionate belief of a handful of people.
Munro, an ex soldier who has realised that war is not the route to peace, attempts to convince 2 warring tribes to find a more peaceful way. Of course, this ends in a brief war. However his influence appears to have lain on the victor as he seeks peace from now on with the vanquished.
There is of course a lot of sacrifice along the way of loved ones, some dirty dealing, some giving up of values and some compromise. But is that a fair price to pay for peace?
It's very, very well acted, and the story flows quickly yet in great detail. Guy Pearce is his usual excellent self and the story is inherently interesting and emotional.
