Darby & Joan - Season 1

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.

As Jack and Joan prepare for her first southern hemisphere Christmas by the beach, a reef dive goes catastrophically wrong, and Joan does all she can to save an injured diver. With a young woman's life in the balance, Joan and Jack discover the accident is really a case of sabotage. The mystery hits home for Jack, who secretly seeks out a woman from his past to make amends for his mistakes.

In a small outback town on New Year's Eve, Joan's search for answers about Ian is waylaid when the motorhome runs out of fuel. Taking jobs as waiters to secure the only room available at the local pub, Jack and Joan are drawn into the illegal tobacco trade. Sparks fly on the dance floor before a real fire breaks out, and Joan is convinced the police have arrested the wrong suspect for the arson.

At a small coastal community, Jack reconnects with Elyse the daughter of Rosemary, the bride Jack left at the altar. A surf lifesaving champion, Elyse believes someone tampered with a drug test, causing her to be banned from her sport just before the national championships. While Jack attempts to clear Elyse's name, Joan is shaken when she discovers the truth about Jack and Rosemary's past.

Jack and Joan's search for a missing boy is complicated by the sudden arrival of Joan's daughter, Rebecca.
 

The return of a familiar figure from her travels enables Joan to piece together the truth about her husband, while an ominous threat from Jack's policing days emerges.
