She is a working mother, good at her work, enjoys her work and is trying her best to get the whole work done. Her husband is a very understanding man, but is also working and is hence quite busy with himself and has little time for the kids too. How the kids are affected by the nanny's continuous presence and how the yearn for their mom to be with them. They see more of their dad than their mom, and the elder daughter (6) makes it very evident that she dislikes her mom's work as it keeps her away from home. The plot moves onto a great project which comes her way, and makes life even more difficult for her. At the end of it all, she just decides to quit her job and stop as it was just driving her family crazy, but she ends up just prioritizing and saying 'NO' to the boss when required.
I thought it was quite dramatic how she decided to quit her job as how many of us would actually do that. If it is a job you have worked so hard to keep, work hard on and then you just walk out? Well, maybe you can if it is driving your life crazy. There is nothing phenomenally great in this movie, but its a decent week night movie.
