The day of Honor is celebrated throughout the Klingon empire, but every
tradition had to begin somewhere. Signi Beta is an M-class planet,
ideal for farming. The Federation wants Sifni Beta, but the Klingon
empire has the stronger claim. Captain Kirk hates to lose the planet
especially to his old adversary commander Kor. Their mutual antagonism
turns into an uneasy alliance, however, when yet another alien fleet
attacks both the klingons and the USS Enterprise. Now, Kirk and Kor
must rely on each other's honor or none of them may survive to wage
their war again.
