An interstellar cataclysm cripples the Klingon Empire's homeworld, leading to their Chancellor seeking peace with the Federation. But covert acts attempt to thwart the peace process and, instead, plunge the Federation into interstellar war – with the Starship Enterprise-A and Captain James T. Kirk caught in the middle. Kirk must clear his name and overcome old prejudices to ensure that the chance for a new era of peace between the Federation and the Klingon Empire does not go to waste.
