Synopsis from AMC:
"Hell on Wheels" tells the epic story of post-Civil War America, focusing on a Confederate soldier (Anson Mount) who sets out to exact revenge on the Union soldiers who have killed his wife. His journey takes him west to ‘Hell on Wheels,' a dangerous, raucous, lawless melting pot of a town that travels with and services the construction of the first transcontinental railroad, an engineering feat unprecedented for its time. The series examines the railroad's institutionalized greed and corruption, the immigrant experience, and the plight of the newly emancipated African-Americans during reconstruction. Over time, "Hell on Wheels" chronicles this potent turning point in our nation's history, and how uncivilized the business of civilization can be.
