Bridget Jones: The Edge of Reason (2004)

Bridget Jones is working as a TV host and still dating her new love, barrister Mark Darcy, for a perfect six weeks. But Bridget is jealous of the time Mark spends with a gorgeous co-worker Rebecca and, despite a vacation meant to smooth things over, ends their relationship. On assignment in Thailand with her disreputable ex, Daniel Cleaver - claiming to be a reformed man - they have a short dalliance, and she is arrested at the airport and temporarily jailed on the false accusation of drug smuggling before Mark, seemingly indifferent, comes to the rescue.
