Harry (John Freeman) sometimes called Larry, sometimes called Eric, is an investigator. There has been a series of murders in the Black Bayou among which was his wife. Harry has a number of issues which include his love of drinking, drugs, and prostitutes. He is under federal investigation. His nephew gives him a marked "lucky" one dollar bill, which Harry immediately spends. The film follows the travels of the dollar bill to connect the story. Harry was a pathetic protagonist. The film was dreary and lacked memorable dialogue or scenes. Guide: F-word, sex, nudity

Moody and well done. It s dark and dicey as thriller should be. good job

Though I do not approve of them flash backs can be used effectively on occasion. This is not one of those occasions. The cast act up to a poor script in this bore of a film and some credit is due. For me it also suffers from a clichéd and predictable storyline in which the baddies are all bad and the goodies are bad too but with reason, and we are expected to sympathise. But it is impossible to identify with the two dimensional characters in this film and any attempted symbolism in a dollar bill is pure tosh. Don't waste your time.

Okay, so maybe the rating is too generous/exaggerated, it is still a good movie to watch. Not amazing, not unique, but definitely watchable.My only objection would be the name ... 1 Buck. It may be catchy but the movie is not about that one dollar bill. How it changes hands is also completely irrelevant to the 'actual' story. Almost as an after thought did the movie makers try to add a good-luck-charm twist to it, and of course that did not work either.The movie is still worth watching.
