On her 43rd birthday, Bridget Jones (Renée Zellweger) is awakened by her mother, who reminds her that her time to have children is running out. She goes to attend the funeral of Daniel Cleaver (Hugh Grant), who is presumed dead after a plane crash. While there she sees her ex Mark Darcy (Colin Firth) and his new wife. They bump into each other somewhat awkwardly, then go their separate ways.
Forty-something and single again, Bridget decides to focus on her job and surround herself with friends. Then she discovers that she is pregnant--but she is only 50% sure of the baby's father's identity.
