The U.S.S. Enterprise races toward a remote planet on a top priority mission to provide medical aid for Dr. Ira Graves, one of the greatest living human minds. Graves' young assistant, Kareen Brianon, has summoned for help against Graves' wishes. An away team, led by Data, beams down to assist the dying Graves. Data develops a particularly strong rapport with the brilliant scientist, who is bravely enduring the final stages of a terminal disease. Shortly after Graves tells Data of his remarkable ability to transfer human knowledge into a computer, he dies.
