A young fan walks TMP set, meets Shatner and we see an unfinished wormhole sequence
This young fan gets to visit the TMP set back in the day, meet William Shatner on the bridge for a chat and then we see an unfinished wormhole sequence where everything's at the normal speed (some of the dialogue is broken up to fit the pacing) and the music isn't finished, etc.
