Fifteen years earlier, on Wyoming's Chalk River in 1875, Thomas Trafford arrives to establish his cattle ranch, along with his accountant and aide, David Melmont. But events take a sour turn when Melmont becomes involved in a horrific crime, which ultimately has an immense impact on the lives of both Eli and Cornelia.

As Eli and Cornelia reach Powder River, a violent attack on his hayrick forces Trafford to make a difficult decision, and Marshall discovers the truth behind the branding. When Melmont finally returns to Wyoming, the stage is set for a violent confrontation.
