The episode, "Chasing Ghosts," finds the NCIS crew preparing for their annual Thanksgiving dinner while trying to solve a cold case that Dr. Wade (CCH Pounder) has been personally tracking for years. They reopen the case when a Navy-issued stolen gun is linked back to a chief petty officer who died 40 years ago.
