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

The giant space amoeba the Enterprise encounters measured over 18,000 kilometers in length. For comparative purposes the planet Earth has an average diameter of just over 12,500 kilometers. See more »

Goofs

When McCoy and Spock leave the bridge after Spock's near-collapse in the opening scene, Kyle, at the helm, is wearing a red shirt. McCoy gives Spock an examination, but does not confine him to Sickbay, so we can surmise that Spock is only off the bridge for a couple of hours at the most. When he returns, Kyle is wearing a gold shirt. See more »

Quotes

Spock: [in shuttlecraft] Oh, and Dr. McCoy, you would not have survived it.

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.
