Meri's offer on the BandB is accepted! But she doesn't have enough cash for the down payment and asks the family for help. Kody steps up, but later, he realizes he doesn't have the money and reneges, leaving Meri to come up with the money on her own.

Meri finds a way to buy the Bed and Breakfast she wants without Kody or her Sister Wives' help. Then, when Janelle hears that Meri closed on the BandB from a stranger on the street, this precipitates another confrontation.

Mitch and Aspyn announce their engagement and the race is on to find a venue! Then, the whole family goes to Utah to help with the official opening of Meri's Bed and Breakfast. At the opening, Kody drops a hint of some MAJOR changes ahead.

Aspyn goes wedding dress shopping but after the fun, Kody drops a huge bombshell. With a weird whiteboard presentation, he tells his wives they need to sell their houses and move. Janelle digs in her heels. She's not going to do this to her kids.

Christine and Meri try to recover the fun relationship they had years ago. Kody and Christine go to check out Flagstaff, AZ. Mariah has something big to announce to the family. Meanwhile Janelle talks to her kids about the move.

Blocked by some of his wives from moving to Utah, Kody pitches Flagstaff AZ. He takes Meri there to look at land and starts to tell the kids. Mitch and Aspyn are busy preparing their wedding but some younger kids have a meltdown about moving.

The Browns go to Flagstaff to look at properties and they are split over which one to buy. Robyn and Christine prefer one and Meri and Kody another. Janelle is the tie breaker and her decision is surprising. They make an offer and the response is sobering.

Aspyn and Mitch are getting married with bagpipes, kilts and lots of flower girls! It's a perfect day but the officiant has lost his voice and the Browns are stressing because they now have to move to Flagstaff within a month!

The Sister Wives announce to the kids that they've bought land in Flagstaff and they plan to move there within a month. Aspyn asks what void are they trying to fill by moving? And Kody secretly has plans drawn up for one giant polygamist house.

Kody sees the plans for his one giant polygamist house and loves them, but will his wives? Just weeks away from leaving their homes in Las Vegas, tensions run high. Robyn presses Kody to settle down and Gabe walks out.

The Brown family is finally moving to Flagstaff. Moving day is chaotic and the dream they are chasing is becoming a nightmare. There's rays of hope, but mostly it's tears as they face an uncertain future and leave so much behind.
