Brielle moves out; Kim strives to cope with the new Brielle-sized hole in her heart as her six children grow up too fast around her; when Ariana tries her hand at improv comedy, she's not sure the acting thing is really her scene.

Brielle spreads her wings and tries to live on her own, only to learn she's more of a homing pigeon; Kim is happy to have Brielle back in the nest, especially since Ariana is looking to get her driver's license and fly the coop.

The Biermanns go to Miami on a family vacation that will culminate in the world premiere of Kim's new song for Key West Pride; while the family takes a swamp boat tour and swims with dolphins, Kim grapples with her fear of performing.

As Kim's Pride appearance approaches, her fear grows; her family rallies behind her to give her the courage to sing her new song; the entire Biermann bunch is in flux, between moving out, switching rooms or going to school for the first time.

The Biermann family takes a trip down memory lane, from Kim meeting Kroy for the first time to their vow renewal in the Turks and Caicos Islands; a look back at Kroy's adoption of Brielle and Ariana and the births of the four youngest Biermanns.

Kim and Kroy plan to take the family on a vacation, going coast to coast in an RV.

The Biermanns head to Nashville; the Littles go hog wild in a candy store; Kim learns some disturbing news about her father.

Still reeling from the bombshell about Kim's dad, the Biermanns say a heartfelt goodbye to Tracey, whose son awaits her in Atlanta. Meanwhile, a visit to the St Louis Arch triggers Kim's many phobias.

The Biermanns face ghouls and ghosts in one of the most haunted houses in the country; Kim drops her phone in the RV toilet.

After days of stormy weather, the sun finally comes out for the Biermanns as they head to Branson, Missouri, or as Kroy calls it, the Vegas for Littles. But the good times only last so long as the RV breaks down in the middle of nowhere.

With their trip half-way behind them, the Biermanns are ready to take on legendary Route 66; first they must survive the night in a busted RV that is stranded in an abandoned parking lot.
