chunk: Kym Buchman (Anne Hathaway) is released from drug rehab for a few days so she can go home to attend the wedding of her sister Rachel (Rosemarie DeWitt). At home, the atmosphere is strained between Kym and her family members as they struggle to reconcile themselves with her past and present. Kym's father Paul (Bill Irwin) shows intense concern for her well-being and whereabouts, which Kym interprets as mistrust. Kym also resents her sister's choice of her best friend to be her maid of honor instead of her. Rachel, for her part, resents the attention her sister's drug addiction is drawing away from her wedding, a resentment that comes to a head at the rehearsal dinner, where Kym, amid toasts from friends and family, takes the microphone to offer an apology for her past actions, as part of her twelve-step program.
