The Enterprise answers a distress call from Federation Outpost #4, a monitoring station on the Federation side of the neutral zone with the Romulan Empire. The outposts were established over a century ago and no one has actually seen a Romulan. The Romulan vessel seems to have some type of high energy explosive device as well as a cloaking device to make the ship invisible. When it appears that Romulans bear a strong resemblance to Vulcans, Kirk must deal with a rebellious crew member. He must also engage in a dangerous cat and mouse game with a very intelligent Romulan commander. Written by garykmcd

Evenly matched adversaries
20 December 2014 | by (Buffalo, New York) – See all my reviews

Things start out on a happy note in this Star Trek episode. A couple of young of the younger members of the Enterprise crew are getting married and William Shatner notes he has the happy duty afforded ship's captains from earth of performing marriages. But a red alert brings everyone to battle stations as a Romulan war bird with functioning cloaking device starts destroying Federation outposts on asteroids near the neutral zone.

We never know what the intention is, to provoke a shooting war or just test the earth alertness. But the Enterprise is the ship on the scene and Shatner enters a battle of wits with a very shrewd Romulan commander Mark Lenard.

Watching these two circle around and try and guess the other's intentions shows us a pair of evenly matched adversaries. Lenard too as does Shatner in every episode shows the strain of command. Both know they're not facing fools. The respect for each other as a representative of a different culture also grows.

In another century Humans and Romulans would still be at each other's throats in Star Trek Next Genertion and Deep Space Nine.

When the phasers and disrupters start firing the tension never lets up.
