Committed vegan, David Graham Scott, follows old colonial relic Guy Wallace as he prepares to go on his last big game hunt and fulfil his ambition to hunt the fearsome Cape Buffalo. It's Guy's last chance to relive his glory days in the African bush and finally lay down his guns.

Guy Wallace lives in a ramshackle caravan on a barren moor in the northern highlands of Scotland. He sits surrounded by memories of the past: a past that includes patrols with the King's African Rifles, periods as a mercenary in the turbulent post-colonial phase and as a tracker for big game hunters. David Graham Scott lives near the old eccentric in the Caithness moors, and as their lives become entwined, an odd-ball relationship develops, as each contends with their staunch, life long views.
