It might refer to a movie or a book titled 'Hours' that is based on a true story. Maybe it's about a specific period of time in someone's life, like a few hours during a significant event such as a rescue operation or a historical moment. The 'hours' could be used to build suspense or show the detailed progression of the true story.
Well, without more context, it's hard to say specifically. It could be about a story where the passage of hours is a crucial element, perhaps a true event that unfolds over a certain number of hours.
