The Enterprise is sent to investigate an enormous cosmic cloud that has entered from beyond the edge of the galaxy and is approaching the planet Mantilles on the furthest edge of the Federation. Sensors indicate the cloud is 800,000 kilometers across and half that in depth, and is composed of a mixture of matter and energy. It enters the Mantilles system and approaches the outermost uninhabited planet, Alondra... and envelops it. Spock scans the area and determines that the cloud is consuming the planet. It then changes course and heads directly toward Mantilles. The Enterprise moves to intercept it in time and Spock notes that if the creature can consume stars as well as planets, it could pose a threat to the entire galaxy. Kirk wonders if they should notify the 82 million inhabitants of Mantilles or if the resulting panic would cause more harm then good. He tells McCoy that the governor is Bob Wesley, a former Starfleet officer and a steady man, and McCoy advises him to contact Wesley and notify him of the situation...

Episode Quotes
Kirk: Am I doing the right thing, Bones? Once I said "Man rose above primitiveness by vowing 'I will not kill today.'"

Spock: The brain could be completely destroyed if we convert the entire ship to energy aimed at the brain's cortex and expend the energy in one mortal strike.
McCoy: That sounds like you're telling us to blow up the ship.
Spock: I believe that is what I just said, Doctor.

Kirk: Spock, what did you perceive?
Spock: The wonders of the universe, Captain. Incredible, completely incredible.
