The Silent Killer Bonanza : Season 12 Episode 22

When an influenza outbreak strikes the Ponderosa, the treatment methods and philosophy of two women from different generations clash. A nurse named Harriet Clinton believes in old-fashioned methods, while the other nurse, Evangeline Woodtree, has studied up on more recent methods. Not helping matters: Doc Martin backs Harriet, in large part because he believes Evangeline's husband is a fraud.
