Kate's first boyfriend, Walter O'Connor, who is now a major league baseball manager, is coming to stay at the Shady Rest. While Kate is excited to see Walter, she is still just as anxious and nervous about him actually asking her to marry him. Regardless of Walter's intentions, his being there makes Sam come to the realization that he too has feelings for Kate. Walter proposes to Kate, but she turns him down.

Young Doctor Craig announces that he's leaving the valley since there just isn't enough business for him and Doc Stuart. Kate thinks she's come up with a solution for him to stay. He should specialize in house calls for people who can't make it into the office. He enlists the help of Floyd and Charley, who wait for him as he makes his stops along the rail line. Homer Bedloe arrives to see what trouble he can stir up to shut down the Cannonball. Bedloe thinks he can use Doc Craig's new business as a reason to shut down the train, because it delays the schedule. Kate figures out what Bedloe is up to. But, she also figures out how to have the doctor treat his patients and still have the Cannonball arrive on time.
