S4·E12 The Decision

Hoss is seriously injured internally and Ben seeks help from the only doctor within 50 miles, who happens to be in prison for murder. Ben talks to the judge, and with some convincing, talks him into letting the doctor look at Hoss. Danny, who works for the Doctor, tells Ben what he saw about the murder. Ben discovers what really happened and proves to the judge that the doctor really is innocent. The judge stops the hanging and Hoss survives.
