In the future, the Westworld theme park offers its visitors the opportunity to experience the Wild West in a large area of land that includes the frontier town of Sweetwater. The town and land are occupied by “hosts”, androids indistinguishable from humans, with advanced programming following a pre-defined set of intertwining narratives, with the ability to deviate from these narratives as visitors interact with them. The hosts repeat these narratives anew each day, having their memories of the previous day erased, until they are repurposed for other narratives or put away in storage for reuse later. For the visitors’ safety, hosts are unable to harm any other life forms, allowing visitors nearly unlimited freedom to engage in whatever activities they want without retribution, including sex and simulated murder with the hosts. A staff, situated in underground facilities, oversees the park, develops new narratives, and performs repairs on hosts as necessary.
