The hero is a video artist with a weekly cable show on Public Access. One morning he is awoken by the sounds of construction coming from the parking lot next to his building. Massive equipment is being moved in and the lot fenced off. Helicopters circle overhead. Instinctively he begins to video the proceedings.
He learns that a tunnel is being dug straight down, 20 feet wide and deeper than any tunnel has gone beneath the city. Signs claim it is part of the city's water project.
