Viva la Mexico

A band of masked robbers hijacks Thomas Durant's payroll train, though a guard shoots one of them in the shoulder. The wounded bandit takes off his mask as he flees to reveal it is Cullen Bohannon. Later, Hawkins (Ryan Robbins), leader of the robbers, gives him his cut of the stolen money. Cullen insists they save their money to start a Confederate colony in Mexico, but Hawkins thinks the men should celebrate their victory and rob more trains. Doc Whitehead (Grainger Hines), an old friend of Cullen's, extracts a bullet fragment from Cullen's shoulder and apologizes for involving him in the gang. The train robbers later drink at a trading post, where a pair of former Union soldiers provoke Cullen into a fight after their comments about Southerners.

At the railway office, Lily tells Durant that railroad construction has been slow and complains about the foreman. Elam (Common) informs Durant that the payroll train was robbed again. Outside, Durant speaks with the Swede (Christopher Heyerdahl), who is tending his wagon. The Swede offers to help restore order in town, but Durant thinks he should continue his new jobs as undertaker and custodian, having been tarred and feathered by the citizens of Hell on Wheels when he was in charge of security.

Nell (April Telek) finds one of the prostitutes murdered in bed, and a crowd watches silently as the Swede loads the body onto his wagon. Durant tells Lily about the murdered woman, a first for Hell on Wheels, and Lily insists they find and punish the killer, but Durant doesn't care, as she was a whore. Lily later gives the Swede money to ensure the dead woman receives a proper burial.

Spying on another train, Cullen recognizes Elam as the guard, then demands to be the first man on the train. As the bandits rob passengers on the train, Cullen barges into the payroll car and orders Elam to hand over the money, explaining that he is saving Elam's life. He refuses, and Cullen urges the robbers off the train, saying Elam overpowered him. Cullen urges the bandits to head straight to Mexico, but Hawkins wants to rob one more train and questions Cullen's motives. Cullen relents and agrees with Hawkins.

Durant chastises Elam for letting Cullen live, but Elam points out he was hired to only protect the payroll. He then offers to help get Hell on Wheels back on track, but Durant hesitates, on account of Elam's race, but says he will consider it. Sean and Mickey are now selling real estate in Hell on Wheels. Ruth approaches Sean with news that her father has been unable to preach for a few weeks and asks for more time on the rent. Sean proposes having dinner to discuss her affairs, but Ruth turns him down. At the brothel, Nell strikes a protection deal with Sean McGinnes (Ben Esler) for 10% of her profits. He later tells Mickey (Phil Burke) she agreed on the condition that they kill the whore's murderer. Standing at the edge of a river, Lily tells Durant that the Sioux tribe considers the land on the other side sacred and her husband Robert wanted to avoid it. Durant disregards her, says the Sioux will be the least of their troubles if they do not get the railroad under control.

Doc urges Cullen to forgo the heist and leave, saying the others are unhappy with him. Later, as the men rob the train, Cullen points his gun at one who is terrorizing a mother and child. The bandit knocks out a distracted Cullen, who wakes to find himself in a prison wagon, where he jokes with a ruffian (Mark Anderako), a fellow prisoner. Later, from his jail cell, Cullen watches a firing squad kill the ruffian, knowing he could be next.
