I'm not sure specifically which 'Snow Fall' based on a true story you are referring to. There could be many works with this title. It might be about a real - life snowstorm event, or perhaps a story that uses snowfall as a metaphor related to someone's real - life experiences like a journey or a struggle during a snowy time.
The true story can give authenticity to the narrative. If it's about a real snowstorm, for example, the details of the actual events like the force of the wind, the amount of snow, and how it affected the environment can make the story more vivid.
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.
