The case of taxi driver and mother-of-two Eileen O'Shaughnessy, who was murdered on November 30, 1997. After sending her last radio message at approximately 8pm, her abandoned vehicle was found with a blood-spattered driver's seat, and her body was discovered 15 hours later in Tinker's Lane, Claregalway. The programme reconstructs Eileen's final hours, in an attempt to prompt people who may know more about the crime to contact the Gardai in confidence.
