When Davis buys a classic table hockey game and sets it up at the DRPD, he finds that he's set events in motion that lead to the ultimate showdown... the Summit Series between Karen and Brent. The whole town takes sides in the tournament, and Hank decides that he now wants Karen as his role-model, after watching both her and Brent train. Lacey joins a new club and nominates Emma for some long-overdue recognition.

To drum up business, Brent gets a sign to put up catchy slogans outside the gas station and coffee shop, but Lacey isn't crazy about his pithy catch phrases. Meanwhile Brent and Emma worry about Oscar's memory after Oscar keeps misplacing his can of Alphagetti. And on a fishing trip, Karen doesn't sleep with Hank.

Hank has another great idea on how Dog River can increase its tourism, and this one actually works, but has far-reaching consequences. Dog River's sudden fame causes an up-swing in business for both Brent and Lacey, and Wanda finds a new talent that she never knew she had: reporting the news, while Davis takes on some duties as a personal body guard for the movers and shakers of Dog River.

Everything is in the pink for Hank, but Brent and Wanda see things a different way than Hank does. Lacey creates Dog River Dollars, and then becomes suspicious that they are being counterfeited. Karen tries to get Davis to think for himself.

A windstorm changes the name of The Ruby; Wanda requires equal rights at work, leaving Brent with more problems than he'd expected; the results of a jam contest leave Oscar concerned about Emma.

When Brent installs a security camera at Corner Gas, he isn't prepared for the private moments caught on tape. Two unlikely conspirators hatch a plan to deal with the camera, and Hank sees the chance to fulfill a lifelong dream when Davis gets a new stun gun. Meanwhile Oscar and Emma's romantic getaway to a fancy resort convinces them there's no place like home.

Hank's comments on Karen's eating habits prompt her to join a spin class at the local gym, and she's shocked to find out who the teacher is. Lacey gets involved in a "Ladies of Dog River" charity calendar, but is shocked to find out just what she has to do to be "Miss April". Wanda buys a new phone for Corner Gas, but won't let anyone use it until it's fully charged, but then it goes missing.

Oscar becomes a school bus driver, and sets so many rules that the kids aren't the only ones having trouble keeping them straight. Hank talks Lacey into letting him advertise The Ruby; Wanda gets hooked on a new energy drink.

In the final 30 minutes before Brent turns 40, Wanda tries to pull off a fireworks display for the occasion that goes terribly wrong. Lacey and Emma disagree over just who should be baking Brent's birthday cake, and Brent is dismayed to discover that his special bottle of scotch has gone missing.

When Brent enters a reluctant Lacey into an eating contest, it tarnishes his reputation and results in a very offended Davis. At the Leroys’, Emma’s new MP3 player allows Oscar to get away with a bit too much. Karen’s auctioneering experience pits Hank and Wanda in a battle of vehicles.

When it is announced that Dog River Days has been canceled, Lacey enlists the help of Davis and Hank to save them. Emma asks Oscar to get rid of the stray cats in her garden, but the task proves more difficult than Oscar thought, and gives Karen a new reputation. Brent fakes an injury in Corner Gas to teach Wanda a lesson.

Hank wants to attract more people to Dog River by building a World's Biggest something and roping Brent into it while Oscar thinks Lacey has a crush on him.

As they kick off their season against a rival team from Stonewood, the local Dog River hockey team finds itself at a crossroads. Brent is a great goalie and is being taken for granted by his teammates, so when an offer from the rival team comes his way, he has to seriously consider his options. Meanwhile the other players are having trouble scoring and might need to take some advice from an unlikely hockey expert. Then team super-fan Emma learns the hard way that you should never mix cars, your husband and a hammer on game night.

Hank believes a dog that helped him is The Littlest Hobo of TV fame, and sets about to prove it, but is constantly outwitted. Brent has problems deciding on what the travel mugs for Corner Gas and The Ruby should look like and thinks that he's being outwitted. Karen and Davis feel their position is threatened when some firefighters arrive in Dog River.

Brent gets tired of hearing Oscar using the same name for everyone, and decides to use what he thinks is a fool-proof way to put a stop to it. Lacey finds out some not-so-nice things about her future when she visits a psychic. Davis finds that it is possible to scare yourself silly, while Wanda and Emma have some difficulties organizing a party.

In the sensational, not-to-be-missed, top-secret final episode, Brent's mysterious disappearance every Wednesday night has the whole town talking. When it is discovered he has been pursuing a lifelong dream, the gang is forced to cope with the news. After six unforgettable seasons, how will Canada's favourite comedy series come to an end?

A Taxman' arrives to investigate Oscar about fuel tax irregularities, Oscar plots with Hank to avoid paying any extra taxes, and Davis sulks about no longer getting free coffee at the Ruby and decides to lash out by writing all sorts of parking tickets.

Things get complicated when Emma forces Oscar and Brent to take Davis along with them on their annual camping trip. Hank's having a first-ever 'good hair day' and tries his best to hold on to more than just the feeling. Lacey and Wanda argue over whose job is more difficult, which leads them to a switch to settle the argument.

Oscar is on a mission to get rid of an errant mouse that has found its way into Corner Gas, but Davis has a soft spot for the little rodent. Wanda hurts her back, and both Emma and Karen try to help her, but aren't very successful. Lacey spoils things for Brent and Hank when they come up with a new game.

When Lacey starts up an 'Employee of the Month' program at The Ruby, Wanda tries to get Brent to do the same, but finds that she has some hurdles to jump before she gets the appreciation she feels she deserves. Hank's new hobby is knitting, much to Emma's dismay. Oscar also has a new hobby: writing for The Howler, and Karen and Davis have to keep him out of trouble.

Hank, Karen and Wanda's willpower is put to the test when they try to make each other break their new year's resolutions. Davis tries to get out of making coffee at the police station and Brent and Emma teach Oscar a thing or two about being a Canadian citizen.

Emma keeps a watchful eye on the citizens of Dog River to ensure the town reigns supreme over Wullerton ('spit') in "Turn Off Your TV Week". Lacey and Oscar find a profitable way to break the rules and Karen and Davis hit the radio airwaves to help everyone cope. Brent finds a creative way to get through a week of no TV with the help of Hank and Wanda.

On their way to the Grey Cup in Regina, the gang from Dog River hit a few snags. Emma and Wanda get physical with a cashier while shopping at their favorite store. Oscar and Hank visit Oscar's crazy old buddy who's not quite the partier he used to be. Karen and Davis try to buy tickets from a scalper. Lacey discovers that getting roadside assistance isn't that simple when you're traveling with a guy who runs a gas station. Meanwhile Brent realizes there may be more to his relationship with Lacey than he thought

Lacey learns what it means to be a victim of success when she invents a new sandwich that becomes a little too popular. Then a spike in traffic convinces the town's mayor to install a traffic light. To pay for it he orders Karen and Davis to crack down on jaywalkers. Hank and Oscar engage in civil disobedience as Brent tries to broker a deal with the pro-traffic light faction to bring peace back to the street of Dog River. Finally, Wanda is excited to get a tattoo until Emma offers to help her design it.

Hank is asked to be Dog River's goodwill ambassador and show an American tourist around. Turns out Hank isn't the best choice and Brent is called in to clean up. Then a new ATM machine at the liquor store draws a loyal following, leaving Lacey to wonder where all her customers have gone. And in an effort to learn French, Karen tries to immerse herself in Dog River's rich but non-existent francophone community.
