Down to the Bone (2004)

This is a noteworthy movie. Irene (Vera Farmiga) is living in New York with her husband and two boys. She works as a cashier, but also struggles with an addiction to cocaine which she tries to keep a secret. She enters rehab during her vacation, but when she comes back to her job her boss discovers her addiction and fires her. She starts an affair with a male nurse (Hugh Dillon) who influences her to resume her consumption of drugs. One night they are pulled over and arrested; when her husband finds out he tells her to move out.

The film has very realistic footage, as though you are watching a documentary or real life television show.
