Such is the premise and storyline for LOGAN'S RUN, released by MGM in 1976 and directed by Michael Anderson. Michael York plays "Logan", a policeman referred to as a Sandman. The "Sandmen" are a police force tasked with tracking down and eliminating anyone who turns 30 years old and defies the government mandate of termination at age thirty. Logan is quite good at his job but soon it is his turn to flee from Sandmen. Logan, tasked with finding a rogue group of "runners"(those who have defied the government and fled rather than be terminated), himself becomes a runner and eventually discovers that there is a world beyond the dome he has lived inside his entire life. (no other spoilers)
The special effects are obviously dated by today's standards but the visuals are often colorful and interesting to watch including a shiny robot named "Box"(played by Roscoe Lee Browne).
