Clothing designer Mary Haines lives in a beautiful suburban Connecticut home with her wealthy financier husband Steven and their 11-year-old daughter Molly. Her best friend since college, Sylvie Fowler, is the editor of a prominent fashion magazine that dictates the latest in taste and style for New York City fashionistas. When Sylvie learns Steven is involved with Crystal Allen, a perfume salesgirl in Saks Fifth Avenue, from chatty manicurist Tanya, she confides in the ever-pregnant Edie Cohen but hesitates to tell Mary, who discovers the news from the same woman after getting a manicure herself. Despite her mother Catherine's exhortation to keep quiet about what she knows, Mary confronts Sylvie first, in a lingerie store, and then Steven, before asking for a divorce.
