Do you know about the plot? If you have seen any work by Harmony Korine (which I haven't seen), the style of this film is apparently similar.
It tells the story of Sarah (Argento), who is a drug addict who funds her habit with prostitution, striptease etc. She had her child when she was fifteen and it was given to a foster family. Now the boy, Jeremiah (Jimmy Bennett), is almost seven, and Sarah wants him back. Well, she gets him and the film is about how they go around the US when Sarah switches from men and pimp to another, sometimes leaves Jeremiah for some years etc. Basically it is a very traditional drug "indie" film... it tries to be artistic so hard.
There is also a fun cameo from -- you would never guess -- Winona Ryder, who plays a child psychiatrist in a quick scene after Jeremiah has been raped by one of Sarah's boyfriends.
