Jim returns home after a year away, determined to reconnect with his family. Fiona's husband, Paul, helps him get a job at the farm, but when they witness some criminal activity at work, Jim's path to redemption hits a roadblock. Then, one night, Fiona has a car accident that will change everything for her family.
After Paul's body is found in the trunk of her car, Fiona is arrested for his murder, and Dez pressures her to recount the day of the crash. In a flashback to weeks earlier, Jim and Paul disagree about how to handle what they witnessed at the farm, and Fiona receives a tempting proposal from Gillian, the wife of Paul's boss.
Paul agonizes over the difficult decision he must make after the gang's ringleader, Kian, orders him to help steal Gillian's prized horse. Gillian has a falling out with her husband, Tom, before a family golf outing, and Jim interviews for a job in town.
Tensions run high on the day of the twin's First Communion when Paul is late coming home and Jim encounters Michael for the first time since returning home. The situation grows even more tense when an estranged family member makes a surprise appearance before the service.
With their relationship now out in the open, Gillian and Fiona plan to go away together with the kids, and Paul wonders if Fiona will leave him for good. Paul tells Jim he cannot keep their secret any longer.
Two weeks before the crash, Fiona's health takes a rapid decline, and she needs stronger medication for the pain. Paul is unable to cope and lashes out. In the present, Dez puts the final pieces of the puzzle together.
