28 Days(2000)

Gwen Cummings is a successful New York writer living life in the fast lane and everyone's favorite party girl. She shares this roller-coaster lifestyle of hopping from dance club to bar to hangover with boyfriend Jasper--handsome, magnetic and equally attracted to life on the wild side. Life is just an execise in debauchery--until Gwen's ungraceful display at her sister Lily's wedding, when she gets drunk, commandeers the limo and earns herself a DUI and 28-days in court ordered rehab. There Gwen comes face to face with a unique set of rules (like no cell phones) and rituals (like chanting) embraced by an assortment of fascinating fellow re-habbers. A jaded city-girl to the core, Gwen is determined not to conform. Then she meets Counselor Cornell, who begins to break through her carefully constructed defenses and force her to take a closer look herself Ultimately, through the companionship of her group as well as a devastating loss, Gwen gradually begins the long struggle to take back her life.
