Doc is using the jail to quarantine people as they fall ill. The common
thread between them seems to be that they all had a dinner meeting together, about the
upcoming German festival, at Bendino's restaurant. Doc, at first, suspects
some type of food poisoning as the culprit, but then discovers it's really
Typhus. Leading citizen Mr. Matthews takes a few of his men over to Bendino's
and beat him to death. Matt arrests Matthews and throws him in jail, much to
Matthew's disdain with all the patients. When Mrs. Saur, a German resident
living outside of Dodge, comes down with the disease Doc has to look
elsewhere for the cause. He sets up an experiment that could cause him to
come down with the disease himself, and possibly die!
