To avert disaster, Gorkon, Chancellor of the Klingon High Council, proposes negotiations between the Federation and Klingon Empire, negotiations that will put an end to the years of hostility between the two powers, and herald a new era of peace and cooperation. Captain James T. Kirk and the U.S.S. Enterprise are dispatched to escort the Chancellor safely into Federation space.
