When they capture one of the thieves, Roosevelt discovers that frontier justice can be flawed. Meanwhile, Elkhorn's operations are disrupted when Merrifield secretly meets with a Chicago beef merchant, prompting Sewall to make a reckless deal with Medora that leads to serious fallout. At the Hotel de Morés, Wilmot Dow and the charming Rosie feel an instant attraction.
