BRAVE NEW WORLD 2

In the first act, we are introduced to daily life in the underground dystopia through the central character, THX 1138 (Robert Duvall), a nuclear-production-line worker. All emotions are suppressed in THX's world through the compulsory use of soma-like drugs, and through ever-present centralised monitoring of all human activities at all times. THX's female roommate LUH 3417 (Maggie McOmie) becomes disillusioned and makes a conscious decision to break the law and stop taking her drugs, and subsequently secretly substitutes inactive pills for THX's medications. As the drug's effects wear off, THX finds himself experiencing authentic emotions and sexual desire for the first time. He and LUH begin a loving relationship, and plan to escape to the "superstructure", where they hope to be able to live in freedom. Before they can attempt this escape they are arrested and charged with having unauthorized sex and not taking state-prescribed drugs.
The second act sees THX incarcerated for his crimes in a white limbo world along with a collection of other prisoners, including Donald Pleasence as SEN 5241 – a sinister technician who has been using his programming skills to try to replace LUH as THX's roommate and became a "prisoner" of the limbo because THX reported him for said programming violations. Some of SEN's dialogue is taken from speeches by Richard Nixon.[2]
Most of the prisoners seem uninterested in escape, but eventually THX and SEN decide to find an exit. They encounter SRT (Don Pedro Colley), who starred in the holograms broadcast citywide. SRT has become disenchanted with his role in the society and is making an attempt to escape. Upon exiting the limbo, THX attempts to find LUH and learns that her identity has been reassigned to a fetus in a growth chamber. This indicates that she has been considered "incurable" and killed. Separated from the other two fugitives, SEN makes a tentative exploration of the limits of the city's underground network. Cowed by what he sees, he returns to the city and is captured by the authorities.

The third act is an extended escape sequence, featuring a futuristic car-chase sequence through a tunnel network. THX and SRT steal two cars, but the latter has difficulty operating the vehicle and crashes into a concrete pillar. It is uncertain whether SRT survives the impact, although the film's script indicates he does not. THX flees to the limits of the city's underground road network while being chased by two police androids on motorcycles, and eventually locates a mode of escape that leads to the surface. The police pursue THX up an escape ladder, but are ordered by central command to cease pursuit at mere steps away from capturing him, as the expense of his capture exceeds their pre-determined budget. THX climbs out of the ground and stands before a magnified setting sun in a red sky, birds intermittently fly overhead, indicating that life is possible on the surface
