The entire area of the USA, a vast empire of the 3rd millennium AD, has been buried under meters of deposits since the catastrophe of 2018. Archaeologist Howard Carson discovers mysterious ruins during his excavations and reconstructs the way of life and cults of the people of the 21st century AD using the tools of 5th millennium AD archaeology. Amateur archaeologist Howard Carson was all the more excited when he stumbled upon traces of this civilization two thousand years later. He was crossing a long-abandoned excavation site when suddenly the ground beneath his feet gave way. Before he knew it, he found himself in a corridor leading to a door behind which lay an unopened burial chamber - clearly marked by a sign reading "Do not disturb" on the archaic-looking doorknob.
