Margaret (Maggs) is a drama teacher at an exclusive girls' private school. She is chronically depressed since being dumped by her boyfriend, Jamie. Alison, Maggs's shrink, suggests that she keep a diary in a bid to help her 'reshape those destructive thought patterns and re-align them to a more productive way of life'. The problem is, whatever Alison says, Maggs ignores. She is on the slippery slide to losing it big time - the star attraction in a reality of her own making as she lurches from drunken one-night stands to humiliating episode after humiliating episode. Will Maggs win back Jamie? Or will she succumb to the devilish charms of the new school janitor, a sexy bit of Irish rough trade?
