Picket Fences follows the lives of the residents of the small town of Rome, Wisconsin, where weird things happen, including cows' udders exploding and a spate of people turning up dead in freezers. Struggling to maintain order in the community is Sheriff Jimmy Brock. Sheriff Brock is married to the town doctor Jill, his second wife. They attempt to raise their three children; Kimberly (from Jimmy's first marriage to Lydia), Matthew and Zachary. Max and Kenny are impulsive and somewhat immature sheriff's deputies.
