Kristen Stewart plays Maureen Cartwright, an American artist working in Paris as a personal shopper for an internationally famous model and celebrity named Kyra, who wants her to purchase the latest in designer clothes and jewelry before they are worn by anyone else. Maureen is unhappy in both her career and location, tempted somewhat by her long-distance boyfriend, who is currently living in the sultanate of Oman. What she's lingering for is some sign from her recently deceased twin brother, who died of a congenital heart condition that she may also fall susceptible to, utilizing their shared gifts as spiritual mediums to make final contact, as they had made a promise to do to prove their belief in life after death, and begin the process of moving on with her life.
