Jax Teller is a mechanic in the Teller-Morrow Auto Shop. But his larger responsibilities come as vice-president of Sons of Anarchy Motorcycle Club (SAMCRO), which does a lot more than fix cars. Founded by his father, SAMCRO is one of the most profitable arms trafficking businesses on the west coast—an arrangement made possible by their ties to the Irish Republican Army. The Sons are well-loved within Charming, but they have no shortage of enemies outside of it. Cops, feds, and rival gangs are all looking to take the Sons down.
