It's been 18 months since we last saw life in Abercorran and Faith and Evan's divorce and custody battle goes from bad to worse. Faith tries to be positive as she juggles being a mother and a lawyer taking on a new case, when someone from her past returns and threatens her happy future.

Unsettled by Rose's reappearance in her life, Faith struggles to keep everything together and focus on Osian's case. Evan decides to keep a closer eye on Faith's every move as Steve battles with his guilt.

As Faith's mind is on helping Mike get justice for Osian and trying to keep Rose away from her family, she loses sight of the effect the divorce is having on her own children - resulting in Alys ending up in trouble with the police. Rose continues to cross swords with Faith.

Faith and Cerys find themselves fighting for Osian at the Court of Appeal in London, as Faith meets up with a friend from the past to get information on Rose. Evan continues to keep a watchful eye on Faith's every move, and Steve bonds with Alys.

Not happy that Faith continues to ignore her attempts to make amends, Rose puts the second stage of her plan into action, jeopardising Steve and Evan's futures. Time's running out for Osian, so Mike makes a difficult decision.

Rose's revenge steps up a gear and sees Faith having to fight for all that's dear to her. Will she be able to save the day or does Rose have more guts than Faith gives her credit for? Life also takes an unexpected turn for Faith as she looks to the future.
