The Enterprise travels to the planet Argo, once a land planet. Now almost the entire surface is covered in water due to volcanic disturbances. Kirk, Spock, McCoy, and Clayton take the aquashuttle down to the planet to study the phenomena and compare it to another planet in the Federation undergoing similar quakes. The aquashuttle touches down in the ocean near the largest landmass on the planet. As Spock and McCoy prepare to take samples, a large amphibious beast, a sur-snake attacks the aquashuttle...

Episode Quotes
Kirk: Look at this place - a tank! I can't command a ship from inside an aquarium!

McCoy: What about you, Spock? What does your logic tell you?
Spock: The captain states the case emotionally, of course, but correctly. I would be of little value to this ship if I am confined to a tank in Sickbay.

Rila: The light is warm and the air is soft. I shall be glad when the surface places can be inhabited.
Domar: The young Aquans have decided to rebuild the great shelters of the air-breathers.
Kirk: Only the young Aquans?
Domar: Senior Aquans cannot adjust to the thought of becoming air-breathers. We will remain at the Aqua city.
Kirk: Don't lose contact with each other. Like your ancestors.
Domar: We will pass ordainments to forbid it.
Rila: And we this time will not ignore them.

Episode Goofs
The aquashuttle lands on Argo in daylight.

However, when Kirk calls the Enterprise for transport, the sky behind him is a night sky.

When Kirk and Spock enter the ancient ruins, Spock's shirt is briefly gold instead of blue.
