As another day of fantasy plays out in Westworld – a vast, remote park where guests pay top dollar to share wild-west adventures with android “hosts” – top programmer Bernard Lowe alerts park founder Dr. Robert Ford about incidents of aberrant behavior cropping up in some recently re-coded hosts. Meanwhile, in the Westworld town of Sweetwater, a rancher’s daughter named Dolores encounters a gunslinger named Teddy in the street – but their predictable narrative is upended by the appearance of a ruthless Man in Black and, later, by a supporting host’s unscripted encounter with an artifact of the outside world.

Maeve's emotions are tweaked by Elsie to prevent a recall; Lee floats his latest narrative to the staff; Bernard and Theresa investigate the extent of a host aberration; two guests arrive looking for different scenarios; the Man in Black enlists a condemned man to learn Westworld's darkest secrets.

Elsie and Stubbs head into the hills in pursuit of a missing host. Teddy gets a new backstory, which sets him off in pursuit of a new villain, leaving Dolores alone in Sweetwater. Bernard investigates the origins of madness and hallucinations within the hosts. William finds an attraction he’d like to pursue and drags Logan along for the ride.

Dolores joins William and Logan on a bounty hunt in the badlands. The Man in Black, with Lawrence in tow, finds a critical clue in his search to unlock the maze. Dr. Ford and Theresa discuss the future of the park. Maeve is troubled by a recurring vision.
