Having found a Federation colony of 100 people completely destroyed, Kirk and the Enterprise have to deal with a nearby Klingon vessel which they believe must be responsible for the colony's destruction. When the Klingon ship is disabled, they, in turn, assume they were attacked by the Enterprise. There is obvious tension between the Enterprise crew and its Klingon enemies. Unbeknown to Kirk and his Klingon counterpart, Kang, this is the work of an alien being that gets its energy from the friction and emotions between sentient beings. The natural animosities between the two parties feed its appetites. When the creature is beamed aboard the Enterprise, it purposely creates tension among the crew, to its benefit. The situation eventually forces Kirk and Kang to work together to defeat it. Written by garykmcd

When the Entity begins to take over the Enterprise by increasing its speed and taking it on a course out of the galaxy, the scene begins to shake suggesting it is a rough ride for the crew. As the scene changes from the bridge to Engineering, Scotty is explaining to Captain Kirk that the engines have "Gone to Warp 9, by themselves". As he is saying these words, the scene suddenly stops shaking. There are no other indications that the ride has suddenly become smooth. The camera operators and/or the special effects team are completely out of sync. See more »

Before "Twin Peaks"...
12 June 2009 | by (The San Francisco Bay Area) – See all my reviews

There was Star Trek. This episode is actually the reworking of the same theme taken from the "Wolf in the Fold" episode, but blown up on an international scale, so to speak.

I say "Twin Peaks" because, if memory serves from what my TV Screen writing Instrustor recited some 20 years ago, the detective in that show makes a comment to the effect of "Can you really believe that a father would murder his own daughter?" ... or words to that effect. Trek was ahead of the curve, yet again, with "Day of the Dove" postulating a possible explanation for all the violence we witness in the news.

Are humans really capable of bloodshed on an industrial scale? Can mankind be so fraught with flaws that he must always reach for the sword to settle otherwise mundane differences? Can this really be the case? Or is there something else at work here? All the racial prejudice, social hatreds, and lusts sparked from aggression, are they really all within us? Regardless of the science fiction in this science fiction piece, the story itself, after examining all the horrible manifestations of man's baser nature, comes to a conclusion of how to settle differences, and presents it to us with some outstanding thesping by the usual suspects, including Michael Ansara playing the epitome of Klingon commanders.

In the days when this remarkable TV show was on the wane, the hard core of fandom was given a treat in the form of this episode. Filled with action, intrigue, a dash of horror and mystery, along with a good deal of fret by both sides of the coin, this episode brings the awful truth of wartime drama to the audience.

Fortunately it is a Star Trek episode, and we are thus treated to the heroics of Captain James T. Kirk who, once again, risks all and holds the honor and inner humanity (Klingonity?) of the opposition in high regard. Kirk and Kang show us the way. The final shot is not just part of the plot and story, but also a very symbolic gesture.

Definitely worth watching.
