Run the mission! Don't get seen! Save the world! A secret city buried one mile under American soil is discovered through the leakage of Von Doom radiation - a type of energy emitted only by time-travel devices. So the Avengers head underground to a weird metropolis forgotten about for decades, because a time machine in the wrong hands is the worst kind of WMD imaginable.
