As the description for the video reads:
The Game provides an early sneak peek at "Ultimate Warrior: A Life Lived ‘Forever,'" an exciting and in-depth chronicle of the WWE Hall of Famer's incomparable life and in-ring career.
The video shows Triple H flipping through the book and giving a look at the deep history it contains, including a few things you won't find anywhere else. That's in keeping with Triple H's own emphasis on the history of professional wrestling and telling its story.
