Louise Shorter, the founder of the charity Inside Justice, investigates the case of Roger Kearney, who was convicted of the murder of Paula Poulton. Shorter examines the evidence, including the lack of forensic proof linking Kearney to the crime, and questions the reliability of the prosecution's case. She explores the possibility that the murder occurred elsewhere and that the evidence was planted, leading her to interview witnesses and experts to uncover the truth behind the conviction.
