The Declaration of Independence is stolen by an extremist group calling themselves The Defenders. Their leader is Col. O'Hara, a highly-decorated ex-Marine and uncle to Major Sarah "Mac" MacKenzie, Harm's new partner. Harm and Mac are sent to negotiate for the return of the Declaration.  Harm is decorated and receives his Distinguished Flying Cross from President Clinton in a ceremony at the White House. 

This is JAG's premiere episode on the new network, CBS, and introduces new characters Mac (Catherine Bell) and Webb (Steven Culp). It also marked the return of Patrick Labyorteaux as Bud Roberts, Harm's aide.
