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.

Matt and Amy may have bit off more than they can chew when they book a mega-sized wedding. When a thunderstorm brings a torrential downpour and sends everyone running, the Roloffs find out the hard way that the bigger the wedding, the bigger the problems.

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.
