CSI: Crime Scene Investigation: A convict, who has been in jail for 18 years based on evidence collected by Catherine in her very first solo case as a CSI, challenges his conviction for murder based on purportedly shoddy evidence by newer, more modern standards. The team opens up and re-investigates the case, applying new techniques and new eyes to very old situations and very old evidence. As one expects with CSI, things don't lead where anyone expected them to go.
