About to enter the Manhattan end of the tunnel, former New York City Emergency Medical Services Chief Kit Latura, now working as a cab driver, witnesses the fireball erupting from the entrance. While racing to help whoever he can he runs into an old EMS colleague, who tells him that the tunnel is severely damaged, and could come down if any wrong moves are made. Kit then checks with tunnel administrators, and finds that most of the old exits have been sealed off or are considered unsafe. Kit makes his way into the tunnel through the ventilation system, risking his life as the massive fans can only be slowed down for a short time.
