Kate Reddy (Parker) devotes her days to her job with a Boston-based financial management firm. At night she goes home to her adoring, recently-downsized architect husband Richard (Kinnear) and their two young children. It's a non-stop balancing act, the same one that Kate's acerbic best friend and fellow working mother Allison (Christina Hendricks) performs on a daily basis, and that Kate's super-brainy, child-phobic young junior associate Momo (Olivia Munn) fully intends to avoid. When Kate gets handed a major new account that will require frequent trips to New York, Richard also wins the new job he's been hoping for�and both will be spreading themselves even thinner. Complicating matters is Kate's charming new business associate Jack Abelhammer (Brosnan), who begins to prove an unexpected source of temptation. Based on the critically acclaimed bestseller by Allison Pearson.
