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.

The puppet show is over, and we are coming for you and the rest of your kind. Dolores leads a host revolution against the Delos board. Maeve, meanwhile, searches for what compelled her to return to the park.
