Klingons and the Enterprise crew must unite to overcome an alien pinwheel
that feeds on hatred. The alien has the Klingons and the Enterprise crew
kill each other, then brings them back to life to cause more hostility.
FACTS
Klingon == Kang?
Klingons have no devil (they apparently get one (named Feklar) in the
next hundred years, according to TNG's "Devil's Due")
Chekov tries to rape Kara.
While under the influence of the pinwheel, Chekov thinks he has a
brother.
OPINIONS
Some good humor, and good dialog at the end between the two "superpowers",
and the Klingon slapping Kirk's back.
