Episode Summary & Review

Summary

On an obscure planet, Kirk smells something that reminds him of the past. And then two crewman die, their ghastly pallor betraying the fact that every red blood cell in their bodies has been destroyed, the hemoglobin neatly removed. A long time ago, very far from here, Kirk was a young Lieutenant about the Farragut when that ship encountered the cause: a mysterious, gaseous cloud that feeds on blood. Now, Kirk is obsessed with destroying the monster that killed his then mentor, the Farragut’s captain Garrovik. Perhaps to an unhealthy degree. Or, given what Spock discovers, perhaps not.

Our Take

A solid Kirk-centric hour that leans on Shatner’s knack for playing guilt-driven stubbornness without tipping into camp. The cloud creature is a thin villain and the middle stretch repeats itself, but the Ensign Garrovick subplot gives the story some real weight. Worth watching for the character study, even if the monster hunt itself is pretty routine.
