The entire Roloff family will be involved in life-changing experiences in the fourth season. The season kicks off with Matt Roloff traveling to Iraq to help a family with three dwarf children in desperate need of medical attention. Matt returns from Iraq with big plans for the farm as the twins, Jeremy and Zach, prepare to graduate from high school. Daughter Molly is cramming for her drivers' license and youngest son Jacob hits the field as his focus on soccer grows. Mom Amy learns to let go—she realizes the kids are growing up and she needs to focus on herself, too. The house continues to undergo an extensive renovation, and the family heads to Florida for a much-needed vacation.
