Delos is a futuristic amusement park that features themed worlds—ancient Rome, Medieval times and the Old West—populated by human-like androids. After two patrons have a run-in with a menacing gunslinger in West World, the androids at Delos all begin to malfunction, causing havoc throughout the park.
