	Synopsis: Clark Palmer, a discredited rogue agent of a rogue federal agency, captures, immobilizes, and restrains Harm on the morning of the first day of a pretrial hearing on charges against a Marine lieutenant colonel accused of violating a chemical-weapon treaty. Harm and Mac are scheduled to prosecute, and a civilian mouthpiece defends. Palmer again renders Harm unconscious inside his apartment, then makes a mold and a mask so that he can impersonate Harm. The hearing starts with Mac but without Harm. However, belatedly the imitation Harm arrives, takes over the prosecution, and soon exposes the defendant to an aerosol containing a nerve gas. Meanwhile Bud helps Harm to escape and to go to the courtroom, where Harm detains Palmer. The admiral and others take the unconscious defendant to A.J.'s office, where they and Harm render help. Bud also gives Harriet a piece of jewelry.
