A busy time for Calum. He must perform a minor operation on "Puppy" but James' advice on administering the sedative doesn't seem to quite work. He also needs to operate on a sick cow, but has some difficulty keeping the owners focused on the task at hand. Calum also receives a visit from Molly McFeely, with whose family he stayed with while in Ireland - and Deirdre decides to visit at the same time. James meanwhile receives an invitation to examine Lord Buttermere's new stallion.
