Sisters consider estrangement from habitual liar after she tells the truth

Three sisters are considering cutting off their fourth sister, Bea, due to her history of lying and harmful behavior. Bea has a long-standing pattern of deceit, including infidelity, theft, and vindictive actions against one sister, Claire. Claire has reached her limit after Bea accidentally admitted to a past lie. The oldest sister, Ann, advocates for a more tolerant approach, viewing Bea as potentially damaged, while Claire feels unable to maintain a relationship with her.
