Fergal Keane talks to people who have taken risks and made sacrifices to stand up for what they believe in. The allegations were horrific: not only abuse but also torture - and possibly murder - in the cellars of a former children's home, Haut de la Garenne, in Jersey. But now police on the island have announced that they have no evidence that anyone was killed there. And Lenny Harper, the police officer originally in charge of the investigation, has been accused of misleading the public. He tells Fergal Keane about the pressures upon him and why it was his desire to bring justice for those claiming abuse that led him to manage the investigation in the way he did.
