The 'a life saved twice story' could be really diverse. It could be a story about a character in a book or movie. Maybe a character was about to be executed in a fictional world but was saved by a last - minute pardon.

There are countless possibilities for such a story depending on the setting, whether it's real - life events, fictional tales, or something in between.
It's likely not a true story. Most often, such titles are part of fictional literature where the plot and characters are created by the author's imagination rather than real-life occurrences.
