Storyline

The Enterprise is sent to investigate the disruption of the Gamma VII-A solar system and the destruction of the U.S.S. Intrepid, staffed solely by Vulcans. When they arrive they find a large dark mass floating in space that is draining energy from everything around it, including the Enterprise. Drawn into the mass, they find a huge amoeba-like creature and Kirk must decide which of his two friends, McCoy or Spock, to send into it aboard a shuttle craft on a mission of no return.

Trivia

This is the second episode where McCoy is referred to as Captain McCoy instead of Dr. McCoy, this time by Spock. The first was Star Trek: The Deadly Years (1967) where Scotty said it. See more »

Goofs

At one point during Kirk, Spock, and McCoy's discussion of using a shuttle craft to determine how to destroy the organism, McCoy crosses over so that he is next to Spock, but the cuts between them show the same exact background, even though they are facing each other (This was done this way because there was no wall on the set behind McCoy, from Spock's point of view).

Quotes

Capt. Kirk: You got something to say?
Dr. McCoy: Technically, no. Medically, yes. Between the stimulants and the pressure, I would suggest that you try to stay off your feet for a few minutes.
Capt. Kirk: I don't have a few minutes, Bones. Maybe none of us do.

Another Roadblock in the Path of the Enterprise
1 May 2014 | by (United States) – See all my reviews

The primary force to be dealt with is a giant one celled organism (a amoeba). it has destroyed a Vulcan ship and all on board. It is up to Kirk and the gang to figure out what to do. It seems that this thing thrives on energy and when attacked simply absorbs it, destroying anything that it encounters. The problem, along with the obvious threat, is that it is beginning to split, and like other mono-cellular entities, it will divide again and again, eventually expanding throughout the galaxy. It is decided that someone must take a shuttle and investigate the interior and a find a way to prevent its forming a second creature. There is quite a bit of byplay between Spock and McCoy. McCoy wants to go into the thing and Spock accuses him of having a martyr complex. Spock is correct when he says he has the qualifications to take the shuttle in. This is a human story where men who know and love one another must make life or death decisions. Kirk chooses Spock even though he knows it is probably a suicide mission. A weakness, I guess, is the reason this thing exists in the first place. If it is a cell, shouldn't there be more of them around. What gave birth to it. It looks just like the one we drew in a biology class lab my sophomore year of high school. This is a tense episode and works pretty well.
