Synopsis: While investigating a Dyson sphere, the Enterprise finds the wreck of the U.S.S. Jenolan, which had crashed while investigating the sphere. On board that ship, locked in a diagnostic loop in the transporter system they discover Captain Montgomery Scott, who had put himself and another crewmember into the transporter system to await rescue. Scotty had been on his way to a retirement planet when his transport ship crashed on the sphere. The Enterprise eventually is trapped inside the Dyson sphere with the sun about to explode and Scotty and LaForge must find a way to save the ship using the wrecked Jenolan. The best part of this episode was watching Scotty reminisce about events from the old series (bonus points if you could name the episodes he referred to) and watching him learn about the technology 75 years after his own day as Chief Engineer. It was also nostalgic seeing the old Enterprise bridge again, even if it was on the holodeck.
