Set against the bleak backdrop of the worst year of the Great Hunger in Ireland (1847 - hence the title), apart from being set in the West of Ireland instead of N. America it's a classic Western revenge thriller type thing. The taciturn anti-hero outlaw gunslinger back from the war, his former commanding officer pressed into service as a tracker by the army seeking to hunt him down.
There aren't a lot of laughs, but it's gripping and affecting stuff with some fine performances from an outstanding ensemble cast. Well worth a watch.
