A Confession

Sian O'Callaghan, 22, goes missing after a Friday night out in Swindon, prompting Detective Sgt. Stephen Fulcher and his team to move fast to have any chance of finding her alive.

The remains of two murdered women are recovered due to the actions of DS Steve Fulcher; the families of Sian and Becky soon discover that, despite the confession of Christopher Halliwell, getting justice will not be straightforward.

Karen Edwards refuses to give up her fight to get justice for Becky; DS Steve Fulcher begins to witness the consequences of his actions, after eliciting a confession from Christopher Halliwell.

When Wiltshire Police find a way to bring Christopher Halliwell to court for Becky's murder, Fulcher realizes that he will have to come face to face with the man who ruined his career.
