Bridget Jones navigates life as a widow and single mum with the help of her family, friends, and former lover, Daniel. Back to work and on the apps, she's pursued by a younger man and maybe – just maybe – her son's science teacher.

Bridget Jones is an average woman struggling against her age, her weight, her job, her lack of a man, and her various imperfections. As a New Year's resolution, Bridget decides to take control of her life, starting by keeping a diary in which she will always tell the complete truth. The fireworks begin when her charming though disreputable boss takes an interest in the quirky Miss Jones. Thrown into the mix are Bridget's band of slightly eccentric friends and a rather disagreeable acquaintance into whom Bridget cannot seem to stop running or help finding quietly attractive.
