The film picks up four weeks (and 70 or so shags) after the original ends. Jones is adorably in love with her human-rights lawyer boyfriend, Darcy. However, happy endings always turn sour in Jones' world and relationship paranoia hits the bumbling journalist. Darcy starts to seem overly conservative, even in the manner in which he folds his underpants, and not-too-perfect Jones fears her man no longer likes her "just the way she is." Add to the scene Darcy's co-worker, the 22-year-old brilliant and gorgeous legal mind, Rebecca (played by Australian newcomer Jacinta Barrett), with "legs up to here," and Jones' jealousy kicks into high gear. What's a girl to do but break up with Mr. Perfect and fly to Thailand with the ex-boyfriend who cheated on her with (gasp) an American? (It's okay: Cleaver is in "shag therapy" now.)
Jones brings along her friend Shazzer (Sally Phillips) to protect herself from the sex-obsessed and charming Cleaver, but Shazzer meets a handsome young man who introduces hallucinogenic mushrooms into their diets. Jones starts seeing pretty colors, and Cleaver seduces her into stargazing on his balcony. He kisses her neck and plays daddy to her gigantic panties, when a knock on the door sounds. Apparently Cleaver's sexual antics are still in their prime-a gorgeous Thai prostitute enters. Jones leaves disappointed and plans an early return with Shazzer. But as she boards the airplane, she is stopped by tazer guns and Great Danes; apparently the parting gift that Shazzer received from her drugged-out Thai vacation friend was filled with cocaine. Jones is locked away in a Thai prison all alone.
Jones quickly makes friends with the Thai prison mates, trading her bra for cigarettes and teaching the women the proper way to sing and dance to Madonna's "Like a Virgin." She realizes just how good she had it with Darcy when the Thai women tell her horror stories of boyfriends who beat them and forced them to take drugs and sell themselves on the street. She is eventually saved from prison by none other than Darcy himself, but his straight-forward manner leaves Jones convinced that he "definitely does not love [her] anymore."
Jones flies back to Britain to find herself surrounded by friends who convince her to go to Darcy's apartment. She does, and Rebecca, who meets her at the door, explains to her exactly why Rebecca and Darcy would never work-definitely the most unexpected plot twist ever.
The film is full of plot twists which topple over the edge of reason. Between magic mushrooms and bad hair days, this British comedy is sure to leave you wanting more. Guess we just have to hope that "Bridget Jones 3" becomes a reality!
