When his estranged 13-year-old grandson Lucas is convicted of an accidental murder and sentenced to hang, Rust travels to Kansas to break him out of prison. Together, the fugitives must outrun the legendary U.S. Marshal Wood Helm and bounty-hunter Fenton “Preacher” Lang (Travis Fimmel) who are hot on their tail. Deeply buried secrets rise from the ashes and an unexpected familial bond begins to form as the mismatched duo tries to survive the merciless American Frontier.
