After Kim's second dance on DWTS, she suffered a stroke, which in turn led to major heart surgery. As a result of that ordeal, this mother of six is ready to take on a new addition to the family. Meanwhile, both Brielle and Tracey are single and spend most of their time swiping left and right all over the Internet. Ariana is finishing up 8th grade while the four little ones spend their days terrorizing their big siblings. Kim loves her ever-expansive, crazy brood and doesn't see any harm in adding one more into the mix.

Kroy is confident that he won't have another run with the Falcons, which means a big move could be on the horizon. Kim is worried about the contents of her closet while Ariana dreads having to start high school in a new city. Meanwhile, Brielle has joined the Biermann payroll as Kim's newest assistant, but struggles to meet Kim's demands.

Motivated by Tracey's passion for animals, the Biermann's join her for a day at the Humane Society. Kim's baby fever reaches an all-time high when she meets the puppies that are up for adoption. Kroy is the only one standing strongly against bringing a dog home, perhaps because everyone's too busy to take care of it. Then again, after checking out the teacup piglet Brielle received as a present, a new puppy suddenly looks a whole lot more appealing.

Kim and Kroy pack up all six kids and head to Kroy's hometown of Hardin, Montana. The younger kids are in heaven, while Ariana and Brielle are just happy to get cell service. As wonderful as it is for everyone to see where dad grew up, Kim longs for the comforts of her own home.

The Biermann kids haven't stopped running around since the plane landed in Montana. Kim loves seeing Kroy in his element, but knows her element is back in Atlanta, with her Starbucks and walk-in closet. As the family vacation comes to an end, Kroy gets a call from his agent and everyone wonders if this is the call that will determine their fate.

After Montana, Kim needs an adult-only break to find her inner peace and Zen. So of course she, Kroy, and Tracey head to the casino – the one place where Kim can fully shut off the rest of the world and focus on her favorite thing: Money. Kim’s strategy is to take out $25k so she can bet big and hopefully win big. Meanwhile, Brielle is upping the ante on her love life and going out on her first date since breaking up with Slade. Will her date be an ace in the hole, or no dice?

Even though Brielle is working as Kim's assistant, she still dreams of becoming a celebrity news reporter. So the family's publicist, has set up a meeting with Access Hollywood in hopes they would offer her a position. Kim and Kroy will be joining her along with KJ, for his first audition. Kim also has a meeting with her skincare company, so when Kroy gets a call from the Buffalo Bills, her anxiety rises as she finds herself traveling alone with a useless Brielle and a hyper KJ.

Dreams are within reach for both Brielle and KJ in Tinseltown. Access Hollywood puts Brielle's improv and kitchen cleaning skills to the test, while KJ's acting audition gets him one step closer to being crowned the next Tom Cruise. Back home in Atlanta, Chef Tracey's new "fancy" menu is ready to be served, but she has a trick up her sleeve that could send the Biermann's back to basics.

With all the uncertainty surrounding her family's future, Kim recognizes that Ariana is in the toughest spot. Being 14 and starting high school is never easy, but in a brand new city it can seem like the end of the world. That's why Kim comes to the rescue with a mother/daughter bonding day. Meanwhile, Brielle is planning her escape to LA, leading Kroy to believe she may not be ready.

Kroy calls for a Biermann family fun day to distract from life's unanswered questions. Things quickly turn from fun and games to sibling rivalry once Kroy offers the winner a prize. Meanwhile, Tracey's latest Internet girlfriend is headed to Atlanta to meet her in person.

Kim gets a not so positive diagnosis on what's been going on with her heart. And if that wasn't enough to put a damper on things, Kroy could get the call at any moment to sign with a new team away from home. With 6 kids, will Kim ever be as stress-free as the doctor has ordered?
