One possible theme could be the idea of perception. It might show how people's limited perception can cause them to miss important things. Another theme could be discovery, like finding something valuable that was always there.
I'm not sure which specific 'hidden in plain sight true story' you're referring to. There could be many stories with this title or concept. It might be about something that was overlooked or unnoticed even though it was right there in front of everyone. Maybe it's a mystery that was solved when someone finally noticed the clues that were always present.
It's not a true story. 'Taken in Plain Sight' is a work of fiction that might draw inspiration from various elements but doesn't represent real events or people. The plot and characters are fabricated to engage and captivate the audience.
