They usually face a lot of public scrutiny. Take the case of some whistleblowers who are made out to be the fall guys. They are trying to expose the truth, but instead, they are painted as troublemakers. They might be isolated and have their reputations damaged. They often find themselves in a situation where they have few allies and are fighting against powerful forces. They have to deal with the consequences of being in the wrong place at the wrong time or being misused by others with more power and influence.
It's completely fictional. The plot and characters of 'The Fall' were imagined by the writers and have no roots in reality. They crafted a unique story for entertainment purposes.
I don't think so. Usually, such names or titles don't imply a true story. It could be pure imagination or a fictional concept developed for entertainment or other purposes.
