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.

Oliver wants to plant wheat on all 160 of his acres, but the local agricultural committee says he can only do eight. Incensed, Oliver takes his complaints all the way to Washington. Surprisingly, Haney sides with Oliver and prepares to fight the National Guard in "The Siege of Green Acres".

Oliver will make considerable more on his apple crop if he gets his to market first. He hires local highschoolers to pick the fruit and uses their old truck to haul them. As the rickety truck suffers numerous breakdowns, the apple prices begin to drop. Finally, Lisa's hotscakes come to the rescue.

Sam Drucker's off for a two-week vacation to visit his sister, leaving Oliver to take over his duties as deputy sheriff. Complications ensue when Oliver demonstrates how to use a pair of handcuffs to Lisa before discovering that he's lost the keys.

Lisa tells the story of how she and Oliver met. During WWII, Oliver's plane was shot down and he was stranded in a tree. Lisa rescues Oliver, but doesn't trust him because he ""spends more time talking than smooching"". After Lisa's story, the farmers of Hooterville discover their crops are being destroyed by some unknown insect. Mr. Kimball identifies it as the ""Bing Bug"". The farmers appoint Oliver to dust all the crops, but not being in the cockpit for years causes trouble for Oliver in Mr. Haney's cheap plane.

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".

It's tomato planting season and Oliver needs some useful weather information. Hooterville relies on WPIXL-TV's Mildred, a little old lady who prances out of her dollhouse, or Walter, the singing weatherman. Both are constantly wrong so Oliver contacts the Weather Bureau which predicts warm days and nights. With the plants in the ground, Hooterville suffers the coldest night of the year. Incredibly, it's Lisa's crepe suzettes that save the crop from the cold.

Oliver misunderstands when the Hooterville bigwigs ask him to be a judge. He thinks he's being appointed an appellate judge but they just want him to judge apples at the county fair. The Douglases travel to New York so Oliver can get some judging advice while Lisa shops for a robe and wig for His Honor.

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.

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.

According to Oliver, every farm wife should be growing her own vegetables so Lisa starts her own garden. Armed with useless pamphlets from Mr. Kimball and a flask of perfume, Lisa begins work. It's hardly a money-saving proposition after she buys a tractor, farm supplies, and hires Alf and Ralph as her housekeepers.

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 starts a feud with the Hooterville Phone Company and launches a campaign to recall its management.

Mr. Trendell turns over the keys of the Hooterville Phone Company to Oliver Douglas.

Oliver sets out to accomplish to changes at the Hooterville Phone Company, now that he's president.

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

Lisa reveals that her mother, the Countess, is going to pay a visit to Green Acres.

Eb decides on a career as a barber and talks Oliver into putting him through a do-it-yourself mail-order barber college.

Oliver decides that all Hooterville farmers should plant rutabagas as their primary cash crop, and initiates a publicity campaign to make America more "rutabaga conscious."

Local inventor "Looney Luke" Needlinger has built a contraption that turns hay into milk. Convinced it will make them rich, Haney and Fred pitch Oliver on investing in the machine, but he thinks they're being conned. After seeing the milk maker in action, Oliver convinces a chemist to give the devise a once-over. What he discovers insures that cows will always have work.

Oliver unintentionally provides the motive for the residents of Hooterville to illegally receive more than $500,000 from the Internal Revenue Service. The locals think all they have to do is write in and state their losses--not understanding that they actually have to file taxes first. Eventually, to get its cash back, the IRS invests in Haney's monkey racing track.
