Darby and Joan

After a vehicular collision with the enigmatic Jack, Joan's first stop in her (covert and novice) investigation into her husband's betrayal brings them to a waterside paradise where a group of old friends have gathered. Then a tragic death puts a stop to the party. Was it an accidental drowning, or is this idyllic land so intensely beautiful, it's worth killing for?

Jack takes a detour to a banana plantation to help his longtime friend and former brother-in-law, Declan, recover a cache of stolen guns. It soon becomes clear that there is more to the gun theft than first appeared, and unraveling the mystery leads to some surprising emotional truths. As Joan begins to get the hang of investigating, she turns her newfound talent to learning more about Jack.

At a remote, mountaintop campground, and after a devastating revelation about Ian's past, Jack and Joan take a moment to unwind with a friendly bunch of fellow tourists. When a high-end caravan is stolen, everyone becomes a suspect and, it turns out, everyone has something to hide. Joan's frustration with Jack puts her life in danger after the thieves return to steal her motorhome.
