Well, without more context, it's really difficult to tell the exact 'Charlie the Gallows' true story. If it's a regional or historical story, it could involve a criminal named Charlie who was hanged on the gallows. Maybe it was a story of justice served in a bygone era. However, it could also be a made - up story that has some elements of truth, like a cautionary tale that was created to keep people in line in a particular society.
Maybe Charlie was falsely accused of a crime he didn't commit and was condemned to the gallows. It could be that there was some sort of power play or vendetta against him.
The movie 'The Gallows' was marketed as being based on a true story, but it's a bit of a stretch. It's a horror film that used the idea of a high school play gone wrong and a haunted gallows on the school's property. In reality, it was more of a fictional horror concept inspired by common horror tropes rather than a strict recounting of an actual event.
