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

Did You Know?


As in the Imperial Starfleet of the Mirror Universe (first seen in Star Trek: The Original Series: Mirror, Mirror (1967)), the regular universe's Klingon Empire uses agonizers on Ensign Chekov. These were developed further as the "painsticks" often seen on Star Trek: The Next Generation (1987). See more »


Just before Chekov forces a kiss on Mara, we see in the close-up shots of her that she is wearing lipstick. Kirk and Spock then arrive and intervene, and in the cutaway shots of Mara during Kirk's subsequent speech, the lipstick is gone. Then Kirk has Spock take her, and as she and Spock exit frame, we see she's wearing lipstick again. See more »

An Alien, Klingons & The Enterprise
13 January 2017 | by Rainey-DawnSee all my reviews

Season 3, episode 7. The Enterprise has found a colony of 100 Federation people that is completely destroyed - no traces people or colonization anywhere on the planet. The Enterprise received a distress call. Kirk, McCoy, Chekhov and a red shirt security member beam down to the planet to find no traces of the colony. The nearby Klingons received a distress call from the Enterprise and their vessel was fired upon leaving many Klingons dead. The Klingons beamed down and confront Kirk and crew about what happened. The Klingons and the Federation have been a peace for 3 years but the Klingon Kang believes that Kirk's ship fired on them to provoke a war. What none of the see is the alien watching them. Chekhov gets upset over remembering his bother Peter and others dying from Klingons years back and the Klingons detain him, but their guns on Kirk and orders Kirk to beam them all aboard. Kirk calls Spock to have all of them beamed aboard then presses a button to alert Spock of impending danger. Scotty and Spock has the Captain and crew filtered out and beams them first into the ship, security team comes in and they finish beaming the Klingons on board, followed by the living Klingons on the Klingon ship. All Klingons are held but Kang, his wife and first officer that will be treated as guests but watched carefully. The alien also entered into the transporter but was able to get on board undetected. Now the Enterprise has several Klingons and an undetected alien on board. This alien will raise the tensions between the Federation and the Klingons. Everything that goes wrong with the Enterprise will be blamed on the Klingons and what happens to the Klingons will they will blame the Federation over an unseen alien. Worse yet, Chekhov wants to avenge the death of his brother - and Chekhov is an only child. To top it off, the Enterprise is flying out of control and medieval weapons of war: swords and axes are appearing on board. Can the Federation and Klingons start working together to solve the mystery of what is really going on? An excellent tension building episode. An alien with intelligence and it's own reasoning for doing these things to both sides. Minds are being taken over by the alien, blame is being thrown back and forth, revenge (Klingons), including false revenge (Chekhov), life support being cut off, insults flying, race hatred and more. This episode feels like "Star Trek" to the fullest extent.
