Plot
In 2293, the Federation starship Excelsior, commanded by Captain Hikaru Sulu, discovers that the Klingon moon of Praxis has been destroyed in a mining accident. The loss of Praxis and the ecological devastation of the Klingon homeworld throws the Klingon Empire into turmoil. No longer able to afford war with the Federation, the Klingons pursue peace. Starfleet sends the Federation starship ''Enterprise'' to meet with the Klingon Chancellor Gorkon and escort him to negotiations on Earth. Enterprise Captain James T. Kirk, whose son David was murdered by Klingons, opposes peace and resents the assignment.
