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.

A pair of guests, first-timer William and repeat visitor Logan, arrive at Westworld with different expectations and agendas. Bernard and Quality Assurance head Theresa Cullen debate whether a recent host anomaly is contagious. Meanwhile, behavior engineer Elsie Hughes tweaks the emotions of Maeve, a madam in Sweetwater's brothel, in order to avoid a recall. Cocky programmer Lee Sizemore pitches his latest narrative to the team, but Dr. Ford has other ideas. The Man in Black conscripts a condemned man, Lawrence, to help him uncover Westworld's deepest secrets.

Dolores, William and Logan reach Pariah, a town built on decadence and transgression - and they are recruited for a dangerous mission. The Man in Black meets an unlikely ally in his search to unlock the maze.

Elsie discovers a possible source of sabotage, while Bernard searches for clues to anomalies in a sector thought to be abandoned. Theresa questions Ford's leadership while Lee encounters a new arrival at Westworld. The Man in Black and Teddy run afoul of a Union garrison in their attempt to cross a border.

With Theresa's assistance, Charlotte Hale aims to expose dangerous flaws in Ford's creations. William, Dolores and Lawrence journey into treacherous terrain. Maeve delivers an ultimatum to Lutz and Sylvester. With his back to the wall, Bernard considers his next move.

Ford orders a reluctant Bernard to conduct business as usual. Maeve looks to change the script for her storyline. Dolores finds it increasingly difficult to separate dreams from reality. Teddy is jarred by dark memories, while the Man in Black recalls some of the travails that brought him to this critical juncture.

Ford unveils his vision for a bold new narrative. Enlightened by Bernard and the Man in Black, Dolores comes to terms with who she is. Maeve sets her liberation plan in motion as Westworld faces a major upheaval.

There is beauty in who we are. Shouldn't we, too, try to survive? Truth is, we don't all deserve to make it. Dolores makes her next move as Charlotte scrambles to protect Delos' most prized asset. Bernard gets closer to the truth and Maeve continues the search for her daughter.

Maeve, Lee, Hector and Armistice have revelations in a new world adjacent to their own - welcome to Shogun World. Dolores makes a decision about Teddy, and Karl Strand discovers something sinister about the hosts' data.

We each deserve to choose our own fate. Maeve continues the search for her daughter, as Dolores calculates her next, ruthless move. Bernard and Elsie break into a new laboratory space and get closer to the truth about Delos.

Hosts and humans converge at the Valley Beyond. This is the end. We will win.

Maeve finds herself in a new park and meets a ghost from the past; Bernard makes his way back to Westworld.
