Gunsmoke - Season 17 Episode 5 New Doctor in Town

Dr. Chapman is arrested by Festus when he tries to sleep in Doc's office even though he has explained that Doc went to Baltimore to hone his medical skills. A letter explains that Doc felt so badly about a little girl's death that he could have prevented if he had been more in tune with modern medicine, that he had to leave. Not many in town are very cordial to Dr. Chapman and when Newly's shop blows up with Newly and Festus in it, they dislike him even more. Festus is all right, but Newly has a bone splinter in his brain and needs an operation. Chapman wins the town by performing the operation and saving Newly's life.
