When Alison's intimidating powerbroker mother comes to visit, Dave tries to set her up with Jake, touting him as a 'gentleman.' A prairie dog infestation has Dave squirming, and one pesky pest named Ralph really makes him work to rid the Tumbleweed of its rodent problem.

After a minor coronary episode, lingerie salesman David Hart decides to try and make his lifelong dream of being a cowboy come true. He makes a deposit on a dude ranch, then finds out that things are not quite as they seem.

After already-divorced Rose throws R.O. out of her house, he comes to the Harts begging - or perhaps demanding - for a place to stay indefinitely. When R.O. – way – overstays his welcome, Alison puts her Western hospitality out to pasture.

As Auggie turns 60, he announces that he's going to die... on the Harts' property, where his late wife is buried. However, Dave needs him to stick around in order to help Duke win a sheep-shearing competition.

Today's Dave's birthday, and it all kicks off with a stampede of cows to outrun! An impactful blow to a singularly sensitive area leaves Dave reeling over the presence of a cattle driver who hopes to drive his prices up exorbitantly. Once he's had time to regather himself, Dave workshops an idea to run a cattle drive himself, forgoing any need for a third-party driver at all. In order to uphold the Sholo way, the Harts must deliver a herd to Carson...

On his tenth birthday, Duke embarks on a rite of passage trip through the Wild West with the rugged and resourceful Jake. Meanwhile, back at the ranch, Alison worries that she may be pregnant, prompting the Hart parents to ponder the possibility of having another child.

Brimming with unsubstantiated confidence, Dave vows to win the Frontier Day buckboard race. When he meets his partner, the elderly widow of a previous champion, however, Dave's hopes plummet. Irked by Dave's judgement, Alison enters the contest and partners with the unyielding frontier widow herself.

Dave's former boss in lingerie sales visits Sholo and holds an impromptu photoshoot for next year's calendar. When the Tumbleweed's well runs try, Auggie tries to locate a water source with a dowsing rod, channeling his profound connection with the land. Zane rescues an ensnared donkey and ventures to impress an alluringly insightful lingerie model.
