Santa Mira, California (founded in 1887) is a small town that is home to the Silver Shamrock Novelties Factory. The town has a curfew and the citizens seem to know what is actually going on in their town. All of them think very highly of Silver Shamrock owner Conal Cochran.
Unknown to the public at large, the town is secretly monitored by Cochran, who has anyone who poses a threat to his plans or simply hates the company killed.
The town presumably went bankrupt after the destruction of the Silver Shamrock Factory, as it was their main source of income.
