Fresh from their shoreleave on Earth, the Nogura is ordered to the Carlson Nebula to investigate several strange readings recently picked up on long range scans. It is a simple mission and after the events on Prolla 5, the crew is rather pleased. Upon arrival at the Nebula, Harrington orders each department into their assigned task. However, before the crew can begin their work an unknown energy wave engulfs the ship rendering the crew unconscious. Each member of the crew awakens at a specific point in their past that had a significant impact on their character’s present. Unable to effect, alter, or change the events of the past; the affected crew is fated to live these events all over again. Forced to reconcile their own past, the crew find themselves trapped; left with no other option to continue.

After coming to terms with their past, the crew awakens to find themselves in the exact moment of their arrival at the Carlson Nebula. With no explanation or reason for how this took place, the Nogura begins their scan of the Nebula only to find all the previous strange readings now gone. Launching a probe, Harrington orders the Nogura to remain and analyze the data. But is all as it really seems? Or did something happen, that no one is aware of?
