The being is the spirit of a light-haired woman who died in an unknown way and haunts school bathrooms across the country, known as the blonde in the bathroom or the Bathroom Blonde Case.
Note on YouTuber count: Synopsis says "three youtubers", IMDb says "Four YouTubers". I should mention the discrepancy or stick to the most specific detail if possible,
