After years of building their dream life in Atlanta, the Biermanns must contemplate leaving it all behind when Kroy becomes an NFL free agent. Kim and Kroy remain optimistic but not everyone is on their side. With Brielle's 18th birthday just around the corner, Kim must come to terms with the idea of moving without her full team behind her. With too many balls in the air, Kim turns to her new assistant Gloria and Chef Tracey for help but notoriously outrageous Tracey's ideas on how to fix them may be too over the top, even for Kim.

The day Kim has been dreading is finally here as Brielle turns 18. With her graduation also on the horizon, Kim worries that she will need a therapist to get her through the next few months. Despite her anxiety, Kim is determined to give Brielle the birthday gift she's been dreaming of, a brand new Jeep. Kroy wants her to earn it and sends Brielle on a scavenger hunt all over town to find her present. An unwanted visitor arrives in the Biermann's front yard and Kim is finally forced to bring her new dogs Turbo and Jet to the vet in an effort to alleviate their ongoing problems.

With no word about where the Biermanns may be moving next year, the family calms their nerves with their annual spring break vacation to Destin, Florida. Instead of leaving her troubles behind at home Kim finds more of them when she has to deal with crying babies, angry alligators, a stressed out Shun, and a surprising revelation from Brielle at dinner.

Chef Tracey has become an invaluable asset to the Biermann clan, but Tracey's over the top stories have Kim and Kroy wondering about her bizarre personal life, which includes fables of her longtime girlfriend, Brooklyn. Unsure if Tracey's girlfriend even exists, Kim suggests the couples go one a double date together. Meanwhile, Ariana is barreling into her teenage years and is bucking against Kim and Kroy's strict rules. Eager to get away from the Biremann circus, Ariana announces her plans to be emancipated when she turns 16.

Kim is invited to make an appearance at Mohegan Sun, a casino near her hometown of Windsor Locks, Connecticut. After 16 years away, Kim decides to take Kroy home for a stroll down memory lane. Stops on the emotional tour include the apartment where a teenage Kim raised Brielle, a revealing lunch with her high-school friends and an impromptu tour of the house she grew up in. While they're away, Kroy asks Brielle's boyfriend Slade to build a dresser for him but Slade wonders if Kroy's request is a favor or a test.

An invitation for Kim to speak at the Atlanta Women's Expo brings conflict to the Biermann home, with Kim set against the idea and Kroy wanting her to overcome her lifelong fear of public speaking. Meanwhile, when Brielle reveals that her dream job is to become an entertainment reporter, Kim sets up a practice interview with recording artist Monica.

Brielle is graduating from high school and Kim and Kroy haven't planned a thing. The Biermanns now have less than a week to pull together a carnival themed party, filled with clowns, fire dancers, and hopefully a monkey. Kim's special graduation surprise for Brielle could mean one less kid in the family nest.

Tracey reveals all the questionable ingredients that can sneak into some of her favorite foods while Kim reluctantly agrees to plant an organic garden. Kim isn't the only one doing something against her will though as Shun's laundry list of things she's looking for in a man has Kim concerned. Kim takes matters into her own hands and decides to set Shun up with her trainer and drags Kroy along to help chaperone.

New graduate Brielle has been so focused on moving to LA with Slade that she has failed to mention some surprising news to Kim and Kroy about her plans for college. Tracey reveals she is newly single and much to Kim's dismay, ready to mingle.

The Biermann bunch spend the weekend at Slade's family lake house. There they meet Slade's mom, Toni, and enjoy a weekend of swimming, boating and tubing. Brielle and Slade ponder their future together when both sets of parents squash the couple's plans to move to California. Tracey bonds with Slade's mom through an unusual method.

With high school graduation out of sight, it's time for Brielle to pack up and get moving, but not before a quick trip to Los Angeles, where she's given the opportunity of a lifetime at E! News. Kim acts as Brielle's biggest cheerleader. Convinced Gloria's job as an assistant is easy, Tracey volunteers to take over her job when Gloria leaves for her wedding.

Kim takes Brielle and Slade to their first psychic reading with Rose who has some very surprising predictions. Meanwhile, a startling discovery is made in the garage as unwelcomed guest brings some friends along with it. With Kroy heading off to camp, Tracey and Kim are left to defend the house.
