The Amish Mafia is secret subculture within the Amish community of Lancaster, Pennsylvania. They provide protection for their people and deliver righteous justice against those who stand in their way.

Levi and his crew hunt down one of their own -- a new crew member who's wanted by local law enforcement. John throws a hut party that goes bad when someone shows up with "green corn."

Levi and his crew run a secret mixed martial arts barn fight, where Jolin must compete to bring in money and maintain respect for the crew. Meanwhile, Ohio's Amish Mafia boss uses John in an attempt to damage Levi.

In a desperate attempt to repay his debts to Ohio boss Merlin, John sets up an illegal buggy race in the heart of Levi's territory. Esther lures Levi away and makes a shocking revelation that may alter the balance of power.

Levi's crew splinters just as his war with Ohio boss Merlin escalates. Each member has to decide for themselves if they will leave or stand by Levi and fight.

The now fractured Lancaster and Ohio mafia crews are asked hard-hitting questions about their lives, the Amish community and the authenticity of the show.
