New York lawyer Oliver Douglas quits his job at the law firm of Felton, O'Connell, Clay, Blakely, Harmon, Dillion & Pasteur and buys a farm in Hooterville, sight unseen. The locals are astounded that Haney had managed to unload the place on someone and try to talk him out of it. Laying her eyes on the dilapidated farmhouse for the first time, Lisa bursts into tears.

Lisa gets her first look at their dilipidated--and empty--farmhouse and is horrified. Oily Mr. Haney, who previously owned the dump, took everything with him, including the bathroom fixtures, and tries to resell them to Oliver. Eb, one of Haney's workers, is hired on as their farm hand. Lisa goes out to meet the locals, most of whom have entered a pool wagering on how long the Douglases will stay. Lisa is ready to immediately return to New York, but after a chat with Kate Bradley, she decides to give farm life a try.

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.

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.

Lisa and Oliver are taken hostage by two bank robbers who hide out in their farmhouse.

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.

Eb becomes obsessed with winning a contest on a Pixley radio station. To identify all the songs, he has to listen day and night. That becomes even harder after Elenaor the cow swallows the radio Oliver just bought Eb for his birthday.

An unlikely but hilarious love affair between Arnold the pig and Cynthia the basset hound captivates the residents of Hooterville.

Oliver sets out to harvest his tomato crops.

When Mr. Haney finds out first that the Douglas farm is the possible site for an interchange for a proposed new highway, he offers to buy back the farm.

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

As part of an agricultural exchange program, Oliver and other Hooterville farmers are offered a chance to join a chartered government flight to Europe.

Oliver and Lisa chaperone Arnold's trip to Hollywood, where he lands a starring role in a motion picture.

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.

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.

The residents of Hooterville are in an uproar when Arnold Ziffel the pig is missing.

Ralph, the lady carpenter, runs away from home and stays with the Douglases after having a fight with her brother, Alf.

The Hooterville farmers have decided that Oliver is ruining the town's image by doing his farming chores in a suit. Oliver eventually gives in to their demand to wear overalls, but they weren't planning on the fur-covered pair that Lisa's dressmaker has designed.

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.

The Douglases try to determine which of their hens is laying square eggs. Once word gets out, Haney and a chicken breeder both want in on the action. Oddly, the cube-shaped eggs don't worry Oliver nearly as much as their toaster that operates when you say the number "five".

The only thing Oliver learns at a farming convention is how to get a hangover. He and Lisa meet up with Charlie, a former gangster-turned-farmer, and Wanda, his floozy dancer wife. The more Charlie talks about his farm, the more Oliver's convinced that his shady days are not in the past.

When the cast takes ill, the Douglases take to the stage in a charity production of The Beverly Hillbillies. After Eb "punches up" a script from the series, Hank Kimball plays Jed Clampett, Oliver appears as Jethro and Lisa portrays Granny with a combination Hungarian/southern accent.

Eb is accused of taking $300 from Sam Drucker's safe when he shows up with a new car, which just happens to cost $300.

Arnold the pig appears in a play at the Hooterville Theater. Lisa arranges for an old friend to give him a chance in show business.

Lisa's Uncle Boris sends her a jar of his incredibly effective cleaning fluid. It removes stains from suit coats and rugs, not to mention green from toupees. Seeing dollar signs, Haney sneaks a sample and has it analyzed; the secret formula ends up being a magical recipe for cabbage soup.
