In July 2013, the discovery of the bodies of two young boys in the back of their father's car sparked a wave of horror in Ireland and overseas.
But in the Co Carlow town where the boys lived, the murders left residents questioning themselves, and the very fabric of their own community.
The first-ever Child Rescue Ireland alert issued for missing children was less than two hours old when Sanjeev Chada drove a car containing the bodies of his sons Eoghan and Ruairi into a wall in rural Co Mayo.
Hundreds of miles away, his wife Kathleen was still expecting the man she loved and the boys she adored to walk through the door at any minute.
Sanjeev Chada survived the impact of the crash to tell a tale which has never fully been told.
Now, 13 years later, his wife Kathleen is finally ready to talk about the sheer scale of the horror inflicted by a loving dad and community man on his eldest son.
Forever My Boys is the story of the lives of two boys who endured unimaginable deaths, of a tormented wife's conflicted love for her husband, and a mother's refusal to ever give up on her sons.
