The Dog River sewer system backs up causing chaos. No one can use their toilets, so Karen and Davis bring in a porta-potty that everyone fights over. Hank sees a business opportunity and starts PÜBER, a mobile outhouse. Wanda thinks she’s responsible for the clog and treks into the sewer system while Lacey bribes Brent to keep the only working toilet in town a secret. Meanwhile, Emma tricks Oscar into updating their family portrait when she finds an unused gift certificate.

Hank accidentally punches Brent and they agree Brent can punch Hank back to settle the score. But when Brent takes his sweet time to make his move, Wanda cashes in on the standoff. Meanwhile, Karen and Davis find moonshine in the woods, which ends up helping Lacey and Emma's fundraiser.

It's cigars and "Battle Brides" night for the women of Dog River but they can't shake Hank from the girls-only event. Meanwhile, Brent stocks a new drink called "Commander Cola" in Corner Gas and Wanda becomes oddly attracted to the product's cardboard promotional military man. Meanwhile, Oscar and Davis buy lottery tickets together and can't stop arguing over how to split the winnings.

Emma sees high art in Hank's hedge-trimming and sells his services around town; prompted by Oscar, Brent tries to collect on the IOUs piling up at Corner Gas, resorting to unorthodox means; Davis and Karen set up the cop shop in The Ruby.

Ike's barn burns down and Lacey wants to help; Lacey organizes a bachelor auction to raise money, attracting a mystery woman who bids high for Brent; the more time the two spend together, the more curious the town gets about the woman's identity.
