At the start of the New Year, 32-year-old Bridget (Renée Zellweger) decides it's time to take control of her life.
She decides to begin keeping a diary, in which she will always tell the complete truth – now, the most provocative, erotic and hysterical book on her bedside table is the one she's writing.
With a taste for adventure and an opinion on every subject, from exercise to men to food to sex and everything in between, she's turning the page on a whole new life. But the fireworks really begin when her charming – though disreputable – boss (Hugh Grant) takes an interest in her.
