City On The Edge Of Forever
- Star Trek: The Original Series
- Season 1, Episode 28
This is one of the first Star Trek episodes to ever dive into time travel. Of course, they work out a “logical” reasoning for the crew going back in time. Doctor McCoy is treating an injured Lt. Sulu when the Enterprise is hit with a time distortion. This causes McCoy to inject himself with a high dose of cordazine, meant for Sulu to treat the injured Sulu. This overdose causes McCoy to be delusional and paranoid, thus causing him to leave the ship as he beams himself down to the planet below.
Captain Kirk and crew find out McCoy entered an ancient gateway that can enter any time or place. Now a heavily medicated McCoy is changing the timeline and both Kirk and Spock must follow him in an effort to stop any damages. They travel to 1930 New York City during the Great Depression. Kirk then begins to fall in love with a woman he meets on this expedition named Edith Keeler. Yet eventually, he realizes that he must allow her to die to save the future.
