We all make mistakes. Moments that change us and the path we are on irrevocably.

For Rachel Allen it was the moment that she let her son's hand slip from hers. For Danny Simpson and Graham Harris it was the moment one of them took it.

Seven years ago Danny and Graham were just children themselves, angry, marginalized and unguided. That was, until they committed a crime so heinous that three families were left devastated. They were no longer just boys. They were monsters.

Released from juvenile detention, it is time for the boys, now men, to start again; new names, new people. But they can never escape who they are or what they did. And their own families, now notorious; the Allens, destroyed with grief; and the country at large have never been able to forget.

They will always be running. They will always be hiding. But are some mistakes too large, the ripples to far reaching, to outrun forever?
