The human race has been relocated to a underground city beneath the Earth's surface where the population is entertained by holographic TV that broadcasts sex and violence, and a robotic police force enforces the law. Society controls all life, all citizens are drugged to control their emotions and behavior, and sex is a crime. Factory worker THX 1138 stops taking the drugs, then breaks the law by falling in love with his roommate LUH 3417; when LUH 3417 gets pregnant, THX 1138 is jailed. Escaping from jail with illegal programmer SEN 5241 and a hologram named SRT, THX 1138 goes in search of LUH 3417 and escapes to the surface with robotic police in pursuit.—Daniel Williamson
