In the aftermath of the disastrous collapse of Westworld in 1983, the Delos Corporation undertook a massive overhaul of its theme park, investing a staggering $1.5 billion into enhanced safety features. After two years of reconstruction, the resort was reopened as an expansive entertainment complex. As a part of a strategically crafted publicity initiative, newspaper journalist Chuck Browning and TV reporter Tracy Ballard received a special invitation to preview the park's newly upgraded attractions.
Before their arrival, Browning arranged a discreet meeting with a Delos insider who was poised to expose damaging secrets about the corporation. However, their exchange was tragically cut short when the informant was fatally shot, leaving Browning with an enigmatic envelope from the dying man, shrouded in mystery and anticipation.
Upon entering the resort, guests found four meticulously designed theme parks: Spaworld, where the effects of aging and trauma had been erased; Medievalworld, Romanworld, and the futuristic Futureworld, offering a space station simulation. Opting for Futureworld, Browning and Ballard experienced a range of robots crafted for both enjoyment and entertainment, including engaging boxing matches and romantic escapades. Their tour was led by the elusive Dr. Duffy, who enthusiastically presented the resort's advanced safety measures and declared Delos' commitment to resolving previous concerns.
As night descended, the duo was astonished to discover a Control Center manned entirely by robots. The following evening, they unknowingly ingested drugged meals, allowing secret medical tests to be conducted while they slept. This unusual procedure was designed to clone the reporters, a process also enacted for visiting dignitaries such as a Russian general and a Japanese politician.
When Ballard abruptly woke up, she felt a profound unease, reminiscent of a vivid nightmare. Nevertheless, she and Browning devised a plan to sneak out and explore the resort's intricate underground passageways. Their after-dark escapade ultimately triggered a cloning machine, resulting in the manifestation of three samurai from the abandoned Eastworld park. Just as they faced capture by these mechanical warriors, Harry, a clever mechanic, came to their rescue, taking them to his quarters where he shared space with a robot named Clark, after Superman's alter ego.
While engaged in an impromptu interview with Harry, their discussion was suddenly interrupted by Dr. Schneider and two security personnel, who escorted them back to their rooms under the watchful gaze of a lingering kiss. The next day, while Ballard was immersed in a surreal dream sequence courtesy of the Delos dream-recording device, Browning stealthily made his way to Harry's quarters, eager to uncover secrets hidden behind locked doors.
Their investigation gained momentum when they discovered that the key to unveiling the mystery lay within the eyes of a robot. With Ballard's inadvertent help, Harry managed to procure the face of a mechanical companion, granting them access to the restricted area. Inside, they stumbled upon eerie duplicates of themselves, alongside astonishingly realistic clones of world leaders. These replicas were programmed to serve Delos' interests and eliminate their original counterparts. As Browning began to unravel the truth behind the envelope from his dying informant, he realized that Delos was cloning influential figures around the globe—a shocking revelation that sent chills down his spine.
In preparation for their escape from the resort on the first available flight, they returned to their quarters, only to find Duffy lying in wait. His malevolent intentions became evident as he unveiled Delos’ sinister plan: by cloning world leaders, they sought to eliminate threats to their interests, effectively ensuring humanity would collapse without “appropriate” guidance. Cloning journalists like themselves would guarantee favorable media coverage, making sure the Westworld tragedy would fade from public memory. Browning’s temper flared, yet Duffy’s unnatural strength overwhelmed him. An intervention from Ballard, who shot at Duffy, revealed his robotic nature as she peeled back the exterior of his face.
Meanwhile, Harry, in his attempt to aid them, confronted Browning's duplicate—the encounter turning tragic for him. Browning and Ballard faced their sinister doppelgängers, each mocking them with personal details from their lives. A gruesome game of survival unfolded, culminating in one member of each pair meeting a tragic demise—the survivor’s identity remaining shrouded in ambiguity. Upon their eventual reunion, Browning embraced Ballard in a passionate kiss, testing whether she was an authentic being or another cleverly engineered duplicate.
Ultimately, their escape from the resort became a reality, yet not before Dr. Schneider intercepted them to affirm their identities as clones. The reporters, facing a precarious choice, reluctantly agreed to craft positive reviews for Delos. However, their pledge was shattered upon witnessing Ballard's injured duplicate stumble towards them on the jetway—a stark reminder that some truths are impossible to bury. As they boarded the plane, Browning revealed to Ballard that his editor was preparing an exposé on Delos that would unmask their nefarious schemes, and that their passionate kiss had indeed been his clever ruse to discern her true identity in the chaos of deception.
