The Bunker: Apocalyptic Wish Fulfillment
In The Bunker, five friends decide to bury a time capsule in the woods, only to find the titular bunker when they start digging. Once inside the bunker, they discover letters from their future selves, who somehow sent a bunker full of evidence back in time to warn their younger selves about the impending apocalypse they will have a part in causing. It turns out this innocuous-looking group of young people includes a future president, a soon-to-be brilliant scientist and several other eventual movers-and-shakers. Heavy stuff for a bunch of recent college grads, no?
