Oliver is frustrated because, among other problems, his new plow won't arrive in time for planting season. Uncle Joe has a solution that, naturally, benefits him as well. He charges farmers one dollar each to enter a plowing contest, promising them free lunch and big prizes. This is all news to Oliver as the neighbors on their tractors start descending on his farm.

It's planting time in Hooterville and Oliver is shocked that the locals make their crop choices based on aches and pains. Back on the farm, Oliver assigns every electrical device a number from one to seven in an effort to keep their creaky generator from blowing. All gadgets up to a total of seven can be plugged in at the same time, but Lisa can't quite grasp the concept.

Lisa is shocked that Hooterville doesn't have a beauty salon. She calls her mother-in-law who ships out her hair dresser, Claude. (She blackmails him with one word: "Scranton".) Setting up shop on the Cannonball, he gives the Hooterville women new hairdos. Now, they're too "beautiful" for farm work.

After Lisa delivers an ultimatum, Oliver hires incompetent carpenters Alf and Ralph Monroe to enlarge the tiny bedroom. The Monroes have just begun moving the walls when the building inspector, the father of Eb's girlfriend, "disapproves" the project and condemns the whole house. Oliver is left with an open air bedroom without a roof.

While fixing the TV antenna, Oliver falls through the roof and sprains his ankle. A parade of Hooterville residents shows up to give their regards while he's off his feet, but instead of sharing the food they've made for him, they crowd him off his own bed to watch Frankenstein Meets Mary Poppins on television.

Oliver is invited to New York to be the guest speaker at a Harvard alumni banquet but he arrives with an unexpected stowaway. Meanwhile, the Ziffels fear that they'll lose Arnold to Mr. Haney, who's trying to take the pig in lieu of a debt that he claims the Ziffels owe him.

Oliver wants to write a folk song about local legend Molly Turgis, a woman so ugly she was run out of Hooterville. Facts are hard to come by, though, because the mere mention of her name causes bad to happen. Lisa feels sorry for Molly and offers to give her a make-over.

Lisa wants to surprise Oliver with a new tractor for his birthday. To keep it out of sight, she has it delivered to the Ziffels' farm. The old couple mistakes it as a gift from Mrs. Douglas, leading Doris to think that Fred and Lisa are having a torrid affair.

Eb's talent for curing sick animals leads the Douglases to send him to veterinarian school. Unfortunately, his college career is short-lived due to one small oversite.

Lisa belives that Oliver's beginning to crack under the pressure of running the farm. After Oliver claims to have seen a spotted horse and a zebra, she calls Doc Watson to give him a checkup. Lisa's attempt to slip Oliver a sedative backfires, resulting in her taking a very long nap.

The "Every Other Wednesday Afternoon Discussion Club" decides to bring culture to the valley by starting the Hooterville Symphony Orchestra. Oliver calls the women "nuts" for considering such a ridiculous idea. Undeterred, Lisa calls her conductor friend Sir Geffory, aka "Poopsie", to come and conduct the orchestra. What he encounters is the Hooterville Volunteer Fire Department Marching Band playing the only song they know.

Mr. Haney has Willie the well-witcher to witch him a new well. But when Mr. Haney has plenty of water, Oliver loses his water. The same thing happens when Oliver has a new well witched, then the Ziffels run out of water. When they get a new well, then Mr. Drucker runs out of water. Oliver decides that Hooterville should open a reservoir. Soon afterwards, everyone has enough water, but when everyone turns on their faucets, they lose their electricity.

When the Ziffels go on a second honeymoon at Niagra Falls, they leave Arnold with Oliver and Lisa. While there, Arnold is drafted by the U.S. Army.

Oliver ends up with a new client named Collins, who turns out to be a very attractive woman, whose first name is Amy, who wants Oliver's legal help about her farm. Oliver has to make regular visits to Amy's farm to help her with her farm. Lisa begins thinking that Oliver is cheating on her, and after hearing Doris Ziffel talking, believes that Oliver is going to kill her, and runaway to South America to elope with Amy. Little does Lisa know the facts, and that Mrs. Ziffel was really talking about the recent episode of her favorite show.

James Stuart from the agricultural department wants to do a film on the pitfalls of new farmers. The locals think "Jimmy Stewart" is coming to make a big Hollywood movie so they all enroll in Haney's acting school. In the meantime, Oliver's farming practices prove especially embarrassing for the camera.

Oliver decides to have an old fashioned Christmas by chopping down a tree off his property. Mr. Haney warns him that it's against the law to chop down a tree on his own property.

So Oilver goes to Drucker's & asks Sam if there's such a law as that. Mr. Drucker tries to sell him an artificial tree with a squirter to squirt the pine ooze out as well as artificial candy canes & popcorn string. Mr. Drucker advises him to get a permit from Hank Kimball, County Agent.

After getting the permit, he finally gets to decorate his tree.

Over @ the Ziffels, Doris is upset that Arnold has an artificial tree & tells Fred that Mr. Douglas had the right idea.

The gang attends the Douglas home to admire the Christmas tree. But they are chased away when Lisa brings out the fruitcakes made out of hotcakes!

Oliver's mother needs bed rest so what better place than her son's farm. All she has to do is ignore Alf and Ralph's drilling, Haney's tour group, a group of dancing Sioux Indians and their chief who think's she's a looker.

The residents of Hooterville flock to nearby Bleedswell for jobs at the new defense plant. To keep people from leaving, Hooterville reopens its old airplane factory to fulfill its contract with the Army--signed during WWI.

Bored and looking for a project, Lisa becomes the head of the "Hooterville Human Humane Committee". She takes her cause to the extreme, declaring everything from duck hunting to selling chicken eggs off limits. Soon, the Douglases house is a zoo and the locals are ready to run her out of town.

Oliver has to choose between being a farmer or lawyer when he gets an offer to practice in Washington, D. C. The official-looking letter, however, has the locals convinced that Oliver is hiding an juicy secret from them. After ruling out tax cheat and counterfeiter, that leaves only one choice: CIA agent.

Tired of Doris' nagging about having to beat their laundry on a rock in the creek, Fred buys a Grabwell washing machine from Mr. Haney. The boat motor in a barrel goes berzerk, spraying water and clothes everywhere before chasing the Ziffels out their front door. Oliver is more than happy to take their case and stick it to Haney in the courtroom.

Oliver decides it would be a great idea for Lisa to make her own jam preserves.

Lisa invests $28 in a 10-year-old's "Electric Company;" to show his gratitude, the young wizard "electronificates" the Douglases' farm.
