A time-travel enthusiast discovers a pocket watch that allows her to alter history, but must navigate through the dangers of the American Civil War era while being pursued by a future version of herself who wants to preserve the timeline, leading to a twist that forces them to work together to find a balance between change and preservation.
Protagonist: A time-travel enthusiast who wants to use the pocket watch to right historical wrongs; Antagonist: A time-traveler from a different era who wants to stop the protagonist from altering the course of history.
The protagonist travels back in time to the American Civil War era and must navigate through the dangers of the battlefield to rescue a key historical figure, while the antagonist tries to sabotage her efforts and ensure the course of history remains unchanged.
The protagonist successfully saves the historical figure, but in doing so, realizes the importance of preserving the timeline. She decides to use the pocket watch to only observe and learn from history, rather than altering it. The antagonist begrudgingly accepts this decision and they both return to their respective eras, leaving the past untouched.
Twist: The protagonist discovers that the antagonist is actually a future version of herself, trying to prevent the catastrophic consequences of altering the timeline. They must work together to find a way to preserve history without sacrificing their own desires for change.
