Al Robertson and Lisa Robertson are telling the story of a marriage that nearly broke under infidelity and then held together through faith. Their personal account is at the center of Faith & Forgiveness, the Lifetime movie set to premiere Saturday, May 16, at 8 p.m.

Al, the eldest son of Phil and Miss Kay Robertson of Duck Dynasty fame, said the story is about a marriage that could have ended but did not. "When unfaithfulness happens in a marriage, so many times, that’s the end of it, but it doesn’t have to be," he said, adding, "Everything can be worked through." He said, "I think the reason I was willing to fight for my marriage was that I had made a lot of mistakes on my own."

The couple first met in a McDonald’s parking lot in West Monroe, Louisiana, when Al was 17 and a senior and Lisa was 15 and a sophomore. They dated on and off before marrying in 1984. After they had two girls, Al served as a pastor at a church where his family had been members for years.

The marriage later ran into a crisis in 1999, when Al became suspicious during the summer that Lisa may have been seeing someone behind his back. Lisa repeatedly denied the accusations. The film says Lisa became involved in an extramarital relationship 15 years into the marriage, but the couple’s account also centers on the strain that grew around isolation, pain and secrecy long before that point.

Lisa said she felt lonely and isolated while her husband was away. She also said childhood abuse shaped her life in ways that lasted for years: "From an early age, at age 7, I was subjected to someone molesting me," she said. "I believe that at age 7, I began to be dishonest with who I was and what I was." She said, "I think the evil one played a huge part in that because he would constantly remind me," and added, "I believe I started on that trail of dishonesty at that point, and that darkness really began there." Lisa said, "As I grew older, it got worse and worse." Years later, she said an old boyfriend contacted her at work.

The film arrives as the Robertsons turn a private collapse into a public testimony, with the finished message landing plainly: their marriage was wounded, but not beyond repair. Faith & Forgiveness asks viewers to watch not for scandal alone, but for how two people decided the ending was not fixed.
