Star Trek: The  Original Series

City on the Edge of Forever: Season 1 Episode 28 Written by:Harlan Ellison

     This is a great episode! In this episode the ship's doctor, Doctor McCoy, jumps into a time portal, and Kirk and Spock follow him. Kirk and Spock jump in the portal a few seconds after McCoy so they are transported back weeks before McCoy shows up.  They jump into New York City during the Great Depression, so it is interesting to see the two, who were born centuries in the future, fit in. I find this fun because this episode was only shot thirty years after the Great Depression, so I was thinking "Shatner, Nimoy you two are from this period." In this period Kirk and Spock find a job at a soup kitchen and Kirk falls in love with their boss. (Of course.) Later Spock finds out she is about to die, she will get hit by a bus, but if Kirk saves her history will be altered and she will be president. I understand why Kirk would save the woman but it would never work out because Kirk will eventually go back to the future. So to me it was obvious that he should just let the chips fall where they may. He decides to not interfer but right before she gets hit McCoy shows up and tries to save her. Kirk stops McCoy. McCoy freaks out because Kirk just let her die! But McCoy does not know what would have happened. They then return to their own time, being gone for only seconds.
