Brent tries to prove his prodigal cousin is a dork while Dog River puts on its annual talent show.

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 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.

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 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.

Brent wants Oscar and Emma to write their wills, which raises their suspicions; they want to ensure that he suffers before he gets anything that they might leave him. The Dog Riverites like the 'drinking and driving' checks more than Karen or Davis expected. And Lacey has a new bulletin board at The Ruby.

Lacey starts a running club in order to train for a Fun Run. Brent becomes a driving force in the club once he joins up. Oscar gets handicap plates for his car, and finds that it changes the way he's treated. Hank gets a job as crossing guard, and takes it very seriously.

A friend of Lacey's visits Dog River and shocks the town with her behaviour. Lacey, using her past experience as a measuring stick, decides that this is just another case of Dog River not accepting outsiders; Hank devises a plan that will settle matters. At Corner Gas, Brent and Wanda try to stop the points card program from going out of control, while Davis considers just how good, or bad, Karen is at undercover work.

It's Dog River's centennial birthday, and Hank wants to honour the town by recreating it in Lego. His quest for artistic perfection causes him to take some drastic steps when he runs out of Legos for his scale-model. Wanda has a birthday as well, and doesn't want anyone to celebrate it. And Karen becomes the town laughing-stock when people find out that she was involved in a sport that no one had ever heard of before.

The children's park in Dog River is going to the dogs, making it unsafe for the kids. Brent comes up with the idea of having a jelly bean jar contest, which everyone likes, until the jelly beans cause strife in the community. Davis relives some of his favourite movies when a convoy of truckers comes through Dog River. Hank joins a new club, which requires him to tell one little lie, which then leads to more and more lies; he somehow manages to involve Wanda into his web of deceit.

Everyone needs some extra cash: Oscar tries to supplement his income by becoming Dog River's official census taker, but Hank already has that job. Finding that their abilities are equal, Fitzy makes them both census takers, and they come up with some unusual methods for counting the denizens of Dog River. Wanda attempts to sell meal replacement bars, with Brent as her underling, but finds that the profits are being eaten up. Lacey misunderstands a situation, and thinks that Karen and Davis are 'involved' with more than just their jobs.

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.

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.
