Likeable playboy Tom has known Hannah for 10 years and, though the two have an unconsummated mutual attraction, views her as his best friend. However, when she returns from a trip to Scotland with the news that she's getting hitched to a wealthy Jock, Tom realises that he will do anything to stop this. There is also a very funny sub-plot with Tom's serial monogamist father about to marry his sixth trophy wife.
