The movie, based on a novel by Allison Pearson, follows Kate Reddy (played by Sarah Jessica Parker), a successful finance executive juggling the demands of her high-pressure job with raising her two young children and maintaining her relationship with her husband (played by Greg Kinnear). Kate's constant struggle to balance competing demands leads to a series of comical mishaps, including a disastrous business trip to New York City and a humiliating encounter with a celebrity client. Along the way, she finds support and camaraderie with her fellow working mothers (played by Christina Hendricks and Olivia Munn) and learns to navigate the challenges of modern-day motherhood while staying true to herself and her ambitions. The film also stars Pierce Brosnan as Kate's charming yet aloof colleague and mentor, and Kelsey Grammer as the voice of her boss and confidant.
