Distrusting outside law enforcement, some Amish in Lancaster County, Pennsylvania, have turned to a small group of men for protection and justice. AMISH MAFIA gives viewers a rare look at this community and the men tasked with maintaining its peace, order, and protection. The 2006 shootings at an Amish school in Lancaster County - during which five young Amish girls were killed and five more seriously injured by a non-Amish milk truck driver - revealed the community's vulnerabilities and need for protection.
