Davis regains his sense of smell in a freak but fortuitous accident. It's a beautiful new world, until the smell of his fellow officer proves too much. Meanwhile Brent realizes just how little he knows about his fellow Dog Riverites and scrabble champ Lacey is challenged by an unlikely some would say inarticulate wordsmith.

Lacey's birthday party is ruined when her deepest fear reveals itself. But then it turns out everyone in town has their own unique fears. Everyone that is except Wanda. So Brent and Hank make it their mission to figure out what freaks her out. Meanwhile, Oscar tries to prove to Emma that he can cook which unexpectedly leads to illicit meetings with Karen. And Hank and Lacey both prove to be pretty bad liars.

With some grunt work ahead at his cousin's farm, Hank is desperate to call in a favour from Brent to help him. The only problem is Brent doesn't owe him any favours and Brent's going to make sure it stays that way. Brent even enlists Lacey's help, only to find out that in a favour war, you have to choose your allies carefully. Meanwhile Karen drives everybody crazy with her new hacky-sack and Oscar is thrilled when he finds a perfectly good pair of pants in the ditch.

Brent enters into the final stage of manhood by buying a big-screen television. He knows this sort of thing can attract a lot of envy, so he's surprised to find he's suddenly the object of pity among his friends. Then Lacey makes the mistake of buying some handmade jewelry from Wanda, realizing you can put a price on friendship. And Oscar and Emma engage in a battle of petty revenge after Oscar criticizes Emma for never putting the lid back on the sugar bowl.

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.

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.

At bingo night, Wanda steps in after the regular bingo caller takes a tumble. She's a hit with everyone except Emma who takes drastic steps to restore her winning streak. Meanwhile Lacey learns that her good old-fashioned home cooking can't compete with the chemically-preserved ""road cookies"" Brent sells at Corner Gas. And, Karen is temporarily suspended from the police force and spends her days hanging out with Brent leaving Hank to wonder what his role is.

Mosquitoes hit the town hard and only Hank seems unaffected. Lacey finally gets a chance to participate in a genuine Dog River activity by contributing to the town's less than impressive time capsule. And Oscar goes back to work at Corner Gas which irritates Wanda, puzzles Emma and sends Brent running to the Ruby, where Lacey's new serve-yourself coffee carafes prove troublesome.

The Leroy family has long been a proud and ineffective curling dynasty but this year a schism in the ranks has Brent and Oscar skipping different rinks. Then when a local senior's hip replacement creates a shortage of female curlers, Lacey finds herself the hottest rookie prospect in the league. Meanwhile Karen is put in charge of safeguarding the famed curling trophy - the Clavet Cup - which turns out to be harder than she thought.

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.

Lacey brings nice wine to dinner at the Leroy home. Unfortunately for Oscar and Emma it opens a door to the wine world that never should have been opened. Meanwhile Hank's life is turned upside down when he wins the lottery. And despite warnings from Brent and Wanda, Karen makes the mistake of talking Davis into getting new shoes.

Lacey gets the job of convincing a good-looking young doctor to set up shop in town. But Lacey and the rest of Dog River get less than they bargained for when the doctor arrives. Then Hank has to find a place to crash while his house is getting fixed, setting off a chain reaction of house swapping as people try to avoid living with him. Finally Brent is annoyed when he inadvertently winds up with what might be a counterfeit 100 dollar bill only to find it has a positive affect on his life.

A big airshow is on nearby and the people of Dog River are very excited. But Lacey's breach of airshow protocol has many in town upset. Thankfully with the help of the Snowbirds, Lacey almost manages to make things right. Meanwhile, business at Brent's gas station hits an unexpected snag while Hank's new corn stand scheme exceeds all expectations. And after a rash of vandalism, Karen and Davis take to the streets on bikes to do some face-to-face community policing. But Karen is oddly reluctant.

With a little help from Oscar, a friendly slow-pitch game in the local beer league gets a lot less friendly. Armed with an array of secret pitches, Brent is ready to lob his team to victory. But the team could be disqualified if 10th member Lacey doesn't make it to the diamond in time. Meanwhile Davis and Karen are only too happy to turn a blind eye to drinking on the team's bench, but they have a harder time ignoring an act of vandalism.

Lacey has just about had it when she finds out about yet another local function that no one invited her to - the Harvest Dance. Is it time for her to stop trying to fit in to Dog River? Meanwhile, Hank falls for a highway worker named Heather. But theirs becomes a forbidden love when the people of Dog River discover something about Heather they just can't accept. Finally Brent and Oscar scramble for reasons not to eat Emma's dreaded jelly salad.

Emma is upset when she finds out that Karen made Brent an offer he couldn't refuse, while Brent is more than happy and tells everyone in town; Hank doesn't follow through on a promise to Lacey, causing her to turn to Wanda for help, but Wanda takes her new role just a little too seriously; and Davis tries every way he can think of to get Oscar to fix his car, but Oscar's fallen in with an unruly crowd, and no longer respects authority.

Brent is being impersonated by a morning radio show DJ, and feels it necessary to prove to everyone that it's not really him talking. Lacey's new delivery service takes off a little more quickly than she'd hoped, and Karen and Davis find out that "work to rule" actually involves "work".

Oscar and Emma enter the digital world with a new thermometer, but trying to agree on the right temperature raises the heat around their house, and even drags Hank into their argument. Lacey disobeys a road sign and feels Karen's wrath over it; a new security height sticker on the door of Corner Gas gives Brent a new mission in life.

Brent and Lacey are shadowed in their jobs by a couple of high school students, but only teach the kids how ~not~ to do things. Hank is now the proud owner of a fondue pot, which upsets Davis. Emma is also upset by the recent divorce of a friend, and she vows to be nicer to Oscar, upsetting someone else in town.

Hank and Brent begin some demolition work on a local barn, but things take a turn for the worse when Oscar offers his help. Davis, looking for some local fame, hires Wanda to shadow him and capture him "in action". Lacey gives Emma a manicure, but it doesn't take.

Karen tries to raise money for charity and comes up with an interesting way to do it: she locks Davis in a cell until she reaches her goal. Hank, trying to help, keeps Davis company. Brent doesn't like Lacey's idea to give Corner Gas a new look; Wanda insists on fixing Oscar and Emma's toilet, even though she doesn't really know how.

After almost dying, Hank decides to follow his dreams and become a rodeo clown. Karen has to give a speech on eyewitness testimony in front of an audience, and seeks help from Wanda. Oscar is tired of being Emma's bridge partner, so Lacey steps in, not realizing what that entails.

In an effort to get Hank to shut up, Wanda and Brent convince him that the internet is the way to go, so that he can fully express all his thoughts. Things get difficult for Brent when he tries to keep everyone up to date on what's happening in Hank's blog, and finds that 'cheat sheets' are just so last century. Lacey is upset over the success of her friend and the food at The Ruby begins to suffer when Lacey feels that she just can't do anything right. Emma, in an effort to cheer Lacey up, invites Lacey to a BBQ, where a cut-throat game of horseshoes takes place. Wanda tries to help Davis save money on his taxes, but things don't go quite as planned.

Lacey finally gets one-up on Brent when he becomes the outsider after learning that, according to the new Dog River global positioning unit, Corner Gas isn't actually inside Dog River. Hank gets a new job as the town's garbage man, but he's a little too 'into' it for Oscar and Emma's liking. Karen tries to help Davis with the ins and outs of practical joking when she discovers that he just doesn't understand either part of the term.

When both Wanda and Davis sign up for piano lessons with Emma, Wanda's competitive drive kicks into high gear and drives everyone crazy. Oscar is upset about the new air pump at Corner Gas, and he's not the only one... the whole town is up in arms over it. Lacey breaks her arm and learns all about Hank's three stages of injuries; meanwhile, Karen is trying to escape some painful cast-signing memories and so avoids signing Lacey's cast.
