While videotaping in a forest, an actress accidentally falls into an open makeshift grave and finds the skeleton of a Navy lieutenant wearing dog tags and dress blues; the lieutenant lacks both middle fingers; Gibbs and company investigate; at the site the boss says that the victim died 11 years ago, and that he knows who killed him. The gang learn that the suspect is now imprisoned in Maryland for the murders of two sailors; Abby says that the same knife killed all three men. Gibbs sends McGee to get a confession for the third murder; while McGee questions the prisoner, other inmates create a disturbance, kill a guard, seize McGee, and take over the visitor center. At McGee's suggestion he serves as a negotiator; he gets a release of the other visitors, then he investigates the death; Gibbs and Ducky join McGee at the prison; Abby makes a curious discovery, and McGee gets a face full. With help, though, McGee works out the problems.
