One warm July morning Mr Phillips climbs out of bed, leaving Mrs Phillips dozing. He prepares for his commute into the city - but this is no ordinary Wednesday. It is a day on which Mr Phillips will chat with a pornographer, stalk a tv mini-celebrity, have lunch with an aspiring record mogul, and get caught up in a bank robbery. It is, as Mr Phillips comes to realise, the first day of the rest of his life - whether he wants it to be or not. All this is both better and worse than being at work.
