Eric Bana is Federal Agent Aaron Falk who returns to his tiny Australian hometown of Kiewarra during an epic drought. He's back for the first time in a couple decades to attend the funeral of a friend - and the friend's wife and daughter, all killed in an apparent murder-suicide. But it's worse than that for Aaron: he left twenty years prior because several people in town believed the death of his girlfriend wasn't a suicide, but that Aaron killed her. That's a lot of history to carry into a town.
The story is based on a mystery novel written by Jane Harper. A small, drought-stricken Australian town is something of an alien location to a city-living Canadian: a brawl at the local pub sees the two police escorting people home rather than to the jail. Well done, inevitably somewhat dark.
