S1 E1: Divorced working mother Christine Campbell (series star Julia Louis-Dreyfus) owns a women's 30-minute workout gym, successfully juggling the daily stresses of motherhood and her business. Her 8-year-old son, Ritchie (series star Trevor Gagnon), has just been accepted into a posh private school frequented by two snooty stay-at-home moms, Marly (series star Tricia O'Kelley) and Lindsay (series star Alex Kapp Horner). Christine's twenty-something slacker brother, Matthew (series star Hamish Linklater), lives with her and also serves as Ritchie's babysitter. Christine gets along with her charming ex-husband, Richard (series star Clark Gregg), even better than when they were married, but her life gets a lot more complicated when she meets Richard's new girlfriend: a nice, young, impossible-to-hate woman also named Christine (series star Emily Rutherfurd)...the "new" Christine.
