Thomas Bradshaw and Tonie Swann are experiencing the classic symptoms of marriage in its middle years: comfortable house, happy-enough daughter and an eerie sense that life might be happening elsewhere. Then Tonie accepts a big promotion at work and Thomas agrees to become a stay-at-home dad. While Thomas is suddenly faced with the daily silence of an empty house, Tonie finds herself alive to previously unimagined possibilities. And at the head of the family, the ageing Bradshaw parents continue their marital dynamic of bickering and petty undermining.
