Bronagh travels to Italy to investigate the past of an Italian suspect, named Danilo Restivo. Could Oki have been murdered by a serial killer?

Reporter Bronagh Munro uncovers new evidence that casts doubt on the conviction of a man who has spent 19 years in prison for murder. Omar Benguit was jailed for killing 26-year-old Korean student Jong-Ok Shin as she walked home from a night out in Bournemouth in 2002. The only evidence to place him at the murder scene came from a heroin addict with a history of making false allegations against innocent people. Police used other vulnerable witnesses to support the addict's story, but some of them tell Bronagh they were pressured to make false statements. She also finds evidence that could give Omar Benguit an alibi for the night of the murder. His lawyer and family are convinced there has been a miscarriage of justice and are using the new evidence to try to take the case to the Court of Appeal for a third time.
