A clandestine love affair sends one man's charmed life into a tailspin in this dark, disturbing drama written and directed by Woody Allen, his first film set and shot in Great Britain and one his few films sans any humor. Chris Wilton (Jonathan Rhys-Meyers) is an Irish tennis player with an impoverished background. Just accomplished enough to make his way onto the professional circuit, but not skilled enough to be a consistent winner, he now works as an instructor at a London tennis club. The wealthy Tom Hewett (Matthew Goode), who is as impressed by Chris's charm and good looks as he is by his game, takes a tennis lesson from the young man. Chris's intelligence and wit also make a strong impression on Tom's pretty sister, Chloe (Emily Mortimer), who soon falls for him. It isn't long before Chris and Chloe are engaged to be married, a match that pleases both Tom and his father, Alec (Brian Cox), a successful businessman who believes Chris has a bright future in his firm.
