Logan's Run takes place in an overpopulated future where every person aged 30 is killed. Logan is a bounty hunter charged with tracking down "runners", or people over the age of 30 who decide that they want to live.
Though the model of the dome city's interior lacks sufficient detail to give it any sense of realism, it was nonetheless constructed on a fairly large scale in order to accommodate the rail system for the miniature maze cars. Many of the buildings in the foreground of the model were three to four feet in height. The buildings were built at differing scales based on their distance from the camera, to give the model landscape a greater sense of depth (a common photographic/special effects technique known as "forced perspective").
