Carolyn McCall is working as a barmaid when TV journalist 'Big Bill' Faraday first muscles his way into her life. Twenty years her senior, Bill is egotistical, sleazy . . . and rich. Within a few months they are married, in a flurry of plastic lobsters and candied salmon (just like Elvis had at his wedding).
Years on, Carolyn and Bill have completely lost sight of what is important in life, but their teenage son, Billy, hasn't. One day he walks out of their lives, turning everything they have ever known on its head.
Carolyn begins an agonising search for Billy in Kings Cross, in homeless shelters and sleazy bars - she's come so far from the life she once knew. Then one day at Central Station she sees Billy in a passing train, and hopes it's not too late to make amends . . .
