Dublin-dwelling Jennifer finds that life with a new baby isn't all it's cracked up to be. She doesn't recognise herself in the mirror, her friends are drifting away, and she worries that she no longer loves her husband. Her own mother passed away of breast cancer when Jennifer was fifteen, and she finds that she has to contend (far more than she had anticipated before the baby's arrival) with an interfering and all-knowing mother-in-law. Her husband, Mark, seems blithely indifferent to Jennifer's predicament as he happily scoffs his favourite meals from childhood - supplied with aplomb by his mother, Geraldine, who has stepped in to 'help' Jennifer after the baby's birth.
Jennifer herself is devastated by her perceived failure at motherhood, after plans for cloth organic nappies, breastfeeding and home-made baby food go awry. After several months she makes efforts to contend with her depression and apathy by embarking on a new fitness regime in time to go back to work part-time, but the return to the workplace does not go as smoothly as she had planned. She becomes increasingly isolated from her once-adored husband and feels that her childless best friends are not making enough effort to understand how radically her life has changed. In particular, she worries about the widening gap between herself and her best friend Ruth, a Louboutin-wearing footloose and fancy-free career girl.
Jennifer's old flame, Aidan comes back into her life, sparking a passionate re-ignition of the love affair that had stalled between them years earlier ... except this time around, Jennifer is married. During one of her clandestine trysts with Aidan, she discovers a lump on her breast. As she undergoes diagnosis and treatment, she realises the significance of what she stands to lose, and rediscovers her love for her husband. But has her husband already developed feelings for someone else?
