The Forest Theory:

Have you ever had a hunch?
A hunch so crazy that it just might be true?
Madison and Sam Have a lot of figuring out to do and not a whole lot of time to do it. Will they make it in time before they and countless others die?

"Why did you leave Carter?"
"It was all because of the theory."
"What theory?"
"The theory of this forest. The theory of life and death."
