In 2020, ecological disaster has driven the wealthy to an underground city. Jason Storm is part of an elite security force called the Tracker-Communicators who protect the city against the surface world survivors who could not afford to escape. Zoey Kinsella, the deceased founder's daughter, joins him as his rookie partner. After a raid by starving surface world survivors breaches the city's force field, Zoey comes to believe they have inside help. Storm acknowledges the possibility but is more concerned with his clashes against the Controller, the leader of the city's security, and his enforcer, Bigalow. The Controller wants to use a cybernetic project to replace the Tracker-Communicators, but he can not find any volunteers.
