Lieutenant Emigh and two other Security men, Barnes and Padilla, accompanied Admiral James T. Kirk, Commander Spock and Dr. Leonard McCoy on a visit to the colony planet Calibus VII. The colony was ravaged by a zombie virus, with which Padilla and Barnes were soon infected and transformed into zombies. When an infected colonist was about to attack McCoy, Emigh pushed him out of the way and was bitten on the neck. Emigh urged McCoy, Kirk and Spock to leave him before he changed.
McCoy subsequently developed a serum to control the zombie virus. Emigh, Barnes and Padilla were restored to sanity, but their bodies remained ravaged and gray-skinned from the virus, which was dormant in their systems, not fully eliminated. The three Security men were forced to remain on the planet, which was quarantined under General Order 7, but McCoy promised them that he would continue working toward a cure.
