Help identifying TV episode

DarthMuppet

Must have been about 20 years ago, I saw an episode of a program like the Twilight Zone. It was set in a space station, filmed in colour, and the characters' accents were American. There was a shapeshifting alien which was going to be able to take over the world if it could kill everyone on the station. There was a twilight-zone-style narration at the end, and it was something along the lines of 'a true hero is someone who gives their life for others, knowing that nobody will ever know'. Is anyone able to identify the series and the episode?

TIA

The Outer Limits (1995-2002), forget what episode. I only watched some of season 1 spotted the episode that gave me nightmares when i was a kid and stopped. Plan on rewatching the series when I rebuild up my courage

Thanks Xenotaris, I have found it - It's The Voyage Home, Season 1 Episode 16. "The true measure of a hero is when a man lays down his life, with the knowledge that those he saves will never know.". Never would have spotted that from the wikipedia entry.
