All four Roloff kids are home for the first time in years as the seventh season begins, which will help as wedding season is approaching and the farm needs a lot of work. Meanwhile, Matt hatches a wild scheme; and the family deal with tragic news.

Matt champions a prefab home an answer to the Roloff's bridal-suite problem, but having it in place and ready for occupation in time for the next wedding is another matter. Meanwhile, Zach decides he wants to move back home.

The Roloffs deals with change in the family dynamic. Included: Jeremy and Molly return to school; at the same time Zach moves into a new house. Also: A series of catastrophes during pumpkin season push Matt and Amy to their limits and leave them wondering whether they have a future together after 25 years of marriage.

Matt stages the inaugural Family Game Day to get the kids more involved in the farm's activities, and it turns into a spirited competition.

Tension between Matt and Amy rises as the first wedding approaches, and Matt's carelessness leaves them unprepared when the bride arrives. Meanwhile, Rocky's health continues to decline.

A month to plan wedding No. 3 gives the Roloffs time to make it their most memorable ceremony to date, but Matt and Amy's new assistant may turn it into one they'd rather forget.

The summer's last wedding demands the Roloffs' attention as pumpkin season is ready to begin, but everything could be put on hold due to rain and Matt's shoulder pain.

Zach asks his dad for advice when a new opportunity arises for Tori and him, but Matt's suggestion that he pay attention to how his parents work together only confuses Zach, who challenges them to spend a whole day side by side.
