Jason Kincaid and the Expedition Inc. team are back for a new adventure.

Mysteries and rumors have surrounded Denver International Airport from the moment it opened its doors (Months behind schedule, just sayin').

Mole people, Illuminati, secret tunnels, you name it, people have said it was under the airport.

But what's really there? Hired to find out, Jason and the team head to Denver, and into an underground adventure.

Too bad someone else already made the discovery and isn't looking to share it.
