A convicted felon claims NCIS framed him for murder a decade ago, so Gibbs investigates and asks Ducky to conduct a new autopsy. Meanwhile, Senior FBI agent Fornell joins the probe, since he was the lead investigator in the original joint FBI and NCIS case.
From murder and espionage to terrorism and stolen submarines, a team of special agents investigates any crime that has a shred of evidence connected to Navy and Marine Corps personnel, regardless of rank or position.
