Credited for helping to modernize the Western genre upon its premiere in 2011, Hell on Wheels centers on former Confederate soldier Cullen Bohannon (Anson Mount) and his role in the Union Pacific's construction of the first transcontinental railroad. Before Season 3 rolls onto screens this August, home viewers can catch up on the frontier drama with Hell on Wheels: The Complete Second Season on DVD and Blu-ray, available today from Entertainment One.

Hell on Wheels Season 3 premieres Sat., Aug. 10 9/8c on AMC.
