28 Days (2000)

After getting into a car accident while drunk on the day of her sister's wedding, Gwen Cummings is given a choice between prison or a rehab center. She chooses rehab, but is extremely resistant to taking part in any of the treatment programs they have to offer, refusing to admit that she has an alcohol addiction. After getting to know some of the other patients, Gwen gradually begins to re-examine her life and see that she does, in fact, have a serious problem. The path to recovery will not be easy, and success will not be guaranteed or even likely, but she is now willing to give it a try.
