The film was shot on location in Shanghai, Dubai and Rajasthan, with interiors done on stage in London.

Most city residents venture outside only after dark since direct sunlight is now considered hazardous to their health. However, many residents still venture outdoors during the day. The government appears to be authoritarian and dystopian. Society is regulated by various codes. The code of the movie title prohibits genetically incestuous reproduction, which may occur as a result of the various medical technologies which have become commonplace, such as cloning.William Geld Tim Robbins, an insurance fraud investigator, is sent to Shanghai to interview employees at a company known as The Sphinx, which manufactures covers, ostensibly insurance cover documents but which in fact regulate the movements of people between cities and inside and outside. Williams assignment is to identify employees who are suspected of forging covers. After interviewing numerous Sphinx employees, he identifies a young worker named Maria Gonzalez Samantha Morton as the forger. He is able to do this using a genetically engineered empathy virus which allows him to gain information from people if they voluntarily reveal something about themselves. Maria tells William that she has the same dream each birthday she is travelling the subway to meet someone she cannot identify. Each birthday she is one station closer to her destination, where she expects to meet the person. William is captivated by her, and instead of turning her over to security, he identifies another employee as the forger. ........
