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.

Elsie and her colleague Ashley 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.

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.

Maeve approaches Sweetwater's longtime outlaw Hector Escaton with a bold proposition. William tries to convince Logan to help liberate Dolores. Teddy and the Man in Black get closer to what they're looking for. Stubbs's suspicions are aroused. Ford cautions Bernard against seeking answers to questions best left unasked.

Why don't we start at the beginning? Dolores remembers she's been to the outside world, William makes a bold business venture, and Maeve begins her quest for her daughter. Someone's always watching.

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.

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.

When you're lost in the dark for long enough, you begin to see - strike the match. Bernard and Ford meet again, and Bernard grapples with the true meaning of the park. The Cradle is under threat and Maeve encounters a scene from her past - but this time, attempts to change the narrative, while the Man in Black discovers just how real the stakes are in Ford's game.

The past is calling, remember what was taken. "Mi cante ki yu ha ya ye." ("Take my heart when you go"). This is the telling of Akecheta's journey to consciousness.

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