Ghosts (S02E07)

The JAG team uncovers a sinister scheme orchestrated by a rogue CIA agent after two assassination attempts on Admiral Chegwidden. Harm and Mac discover that several members of the admiral's old SEAL team have died under suspicious circumstances. Their investigation reveals that Chegwidden and his team were involved in a CIA-controlled SEAL operation during the Vietnam War. They suspect the murder attempts are linked to this mission and delve deeper, uncovering a plot to silence all witnesses to a horrific event from that time. When the assassin kills Chegwidden's girlfriend, he resolves to confront the threat himself, even at the cost of his career.
