Bill Paxton plays a character who is a hustler and a "gypsy". He belongs to the tribe of so called Irish Travellers who live in a trailer park, isolated from the rest of the mainstream. They live their lives by scamming people, pulling tricks and making easy money in the rural south. There are certain unwritten codes of conduct that these people live by. Outsiders are strictly fobidden, and "tricks" are meant to support Travellers extended families and elderly.
So one day, a young man (played by Mark Wahlberg) apeears to the clan that used to be his father's before his father decided to marry a woman who was an outsider herself. Suddenly an orphan, this young man decides to turn to the only family he knows for help. He is not easily accepted and it takes Paxton's character Booky to take him uder his wing in order to help me learn how to make money on the road.
All is well, until one day, during one of their "tricks" a woman (played by Julianna Margulies) comes between these two men. Loyalties are tested. One day, they decide to pull a big scam that tips off another tribe of gypsies (these are of the Eastern European kind). A sort of war erupts and it is a kind of game where there are no prisoners. Winner takes all.
I liked the movie. It is better that any type of gangster/mob movies. These are people who pull tricks, but will not shy away from killing is all other resources are exhausted. It is also a story of basic human need to be surrounded by love and people who can save us from loneliness, unhappiness and despair.
