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.
