Andrea: You ever try explaining to your parents why your DNA makes you the only candidate for a time jump?
Daniel: And they understand you're never coming back?
Andrea: I reminded them that Adolf Hitler was responsible for the deaths of sixty million people. Fathers, mothers, children. And that only I can stop that from ever happening.
Host : What if you had a chance to go back in time, to save millions of lives by killing one man? Andrea Collins will soon discover this mission to be more difficult than she ever imagined, as she takes a one-way trip into The Twilight Zone.
Host: A moment of silence for Andrea Collins. She sacrificed her life for the good of mankind, but she also created the very monster she sought to destroy. History can never be changed. Not even in The Twilight Zone.
Another concept explored extensively in previous TZ episodes, including "Back There" and "No Time Like the Past." The latter explored the concept of killing Hitler as well.
