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.

After breaking up, Bridget Jones' happily-ever-after hasn't quite gone according to plan. Fortysomething and single again, she decides to focus on her job and surround herself with old friends and new. For once, Bridget has everything completely under control. Then her love life takes a turn when she meets Jack. A week later, she runs into Mark before she finds herself pregnant, but with one hitch - she's not sure of the identity of her baby's father - Mark or Jack.

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.
