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.
