I think the fact that it is sourced from real - life situations and real people's experiences is what makes 'Perfect High' a true story. It might have been created by gathering information about real events, interviewing people involved, and then crafting a narrative around those facts. So, it's not just a fictional tale but has roots in reality.
Yes, it was. The movie was adapted from the actual circumstances of a powerful storm that caused significant damage and had a major impact. The story was fictionalized to some extent for dramatic effect, but it originated from a real weather phenomenon.
