The beloved Roloff family - husband and wife Matt and Amy, and their children Jeremy, Zach, Molly, and Jacob are back. Matt and Amy are making their dreams come true by turning their farm into a wedding venue.

The Roloffs book their first wedding and the whole family pitches in to try to make the event a success. Way behind schedule and dangerously over budget, Matt and Amy are desperate to finish construction on the new property any way they can.

When Molly moves out, Amy takes her little girl off to college and leaves Matt to manage a wedding event. But when the horse wranglers are late and Matt's farm manager drops the wedding cake, the day turns out to be anything but a fairy tale.

The Roloffs pull out all the stops to transform the farm into Hawaiian paradise for their final wedding of the season. Matt's obsession with creating a flaming volcano proves to be an explosive idea with Amy and when Zach announces a major life change.

Matt and Amy decide to throw a big bash at the new wedding farm venue to celebrate their 25th wedding anniversary. But the planning is anything but a party when Matt and Amy find themselves at odds over every detail.
