THX 1138

In the dystopian future, sexual intercourse and reproduction are prohibited, and use of mind-altering drugs is mandatory to enforce compliance among the citizens and to ensure their ability to conduct dangerous and demanding tasks. Emotions and the concept of family are taboo. Workers are clad in identical white uniforms and have shaven heads to emphasize uniformity, likewise with police androids who wear black and monks who are robed. Instead of names, people have designations with three arbitrary letters (referred to as the "prefix") and four digits, shown on an identity badge worn at all times.
