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.

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.
