Theresa (Julianne Moore) is a media mogul who seemingly has it all; a thriving business, a handsome artist husband (Billy Crudup), a charming family and an idyllic home. When Theresa invites Isabel (Michelle Williams), an American living in India who has devoted her life to helping orphans, to meet her in New York, they are supposed to be discussing a generous donation that Theresa has agreed to. While Isabel thinks she'll immediately be returning to her beloved orphanage, Theresa has other plans, insisting Isabel attend her daughter's wedding at the family's estate. The joyful event becomes a catalyst for a revelation that upends the lives of both women.
