After breaking up with Mark Darcy five years earlier, Bridget Jones' happily-ever-after hasn't quite gone according to plan. Fortysomething and single again, she decides to focus on her job as top news producer and surround herself with old friends and new. For once, Bridget has everything completely under control. Then her love life takes a turn - while a weekend away at a music festival, she meets a dashing American named Jack, who is everything Mark is not, and spends a night with him. A week later, she runs into newly-separated Mark, and has a one-night dalliance. In an unlikely twist, she finds herself pregnant, but with one hitch - she's not sure of the identity of her baby's father - Mark or Jack.
