Harvest Sunday proves to be a trying time for the practice. Seigfreid seizes the opportunity to teach Callum cleanliness by example, forcing him to watch "the perfect operation" on a sick cow. Unfortunately, the operation doesn't go according to plan. When Callum is chased by a bull, James goes to his aid.

Siegfried is determined to discover who shot Korean War veteran Jacob Pearson's dog. The suspect is Captain Crawford's willful and surly 20-year-old son, Hugh -- a young man with problems beyond his pompous father's control. Both James and Siegfried have extraordinarily little success in extracting payment from wily farmer Dennis Pratt -- until they discover he may be sneaking his cows onto a neighboring farm to enjoy better grazing.
