Captain's log, stardate 5843.7. The Enterprise is in the grip of a raging epidemic. Three crewmen have died and twenty-three others have been struck down by Rigelian fever. In order to combat the illness, Dr. McCoy needs large quantities of ryetalyn, which is the only known antidote for the fever. Our sensors have picked up sufficient quantities of pure ryetalyn on a small planet in the Omega system. We are beaming down to secure this urgently needed material.
