THE NEW ADVENTURES OF OLD CHRISTINE stars Julia Louis-Dreyfus ("Seinfeld") in a comedy about a divorced working mom who is successfully juggling the daily stresses of motherhood and her business, while maintaining her fantastic relationship with her ex-husband…until his young, new girlfriend enters the picture, instantly complicating her life. Christine Campbell has a busy life--after all, she's prone to taking NyQuil to get to sleep and leaving voicemail messages to herself in the middle of the night. But it's a good life: she owns a women's 30-minute workout gym, and her 8-year-old son, Ritchie (Trevor Gagnon), was just accepted into a posh private school where she encounters two snooty stay-at-home class moms, Marly (Tricia O'Kelley) and Lindsay (Alex Kapp Horner), who can't seem to grasp the concept that Christine actually works. Her 20-something slacker brother, Matthew (Hamish Linklater), lives with her and has an uncanny knack of getting Ritchie to do anything Christine can't. Also, she gets along with her charming ex-husband, Richard (Clark Gregg), even better than when they were married. But easy street is suddenly filled with a major pothole when Christine discovers that Richard has a new girlfriend: a young, nice, impossible-to-hate woman also named Christine…the "new" Christine (Emily Rutherfurd), and that doesn't sit very well with "Old Christine." Now, as Christine realizes that Richard is moving on with his life, it dawns on her that maybe it's time for her to take that same leap.
