What would you do if you found out that you and your friends would be responsible for the end of the world? That’s the very question five friends – Grady, Heidi, Natasha, Daniel, and Billy – had to face in the opening pages of The Bunker. As they were about to bury a time capsule, they uncovered a bunker that contained letters written by their future selves warning them about the impending apocalypse – that they caused. Knowing that they cause a near extinction of the human race, the friends are each faced with their own demons and internal struggles. Can they change the future, or is their destiny written in stone? Are the letters even real?
