This first original series from BBC America is set in the mid 1860's New York, when famine and poverty runned the streets filled with legal and illegal immigrants and centers on a policeman (Irish mind you, for you history geeks this will mean a lot) and his investigations in the horrid neighbourhoods of NY, in the aftermath of the civil war.
It is actually quite good, although I thought it would be more 'the killing' like in terms of its tone, but hell, I was entertained for 45 minutes and I want to see more.
