Reeling from the combined pressure of an ATF crackdown and an unprovoked murder, the Sons face a far more deadly threat from a cold-blooded enemy who will stop at nothing to drive them out of Charming for good. As Jax and Clay square off over questions of leadership and loyalty, lines are drawn and chaos reigns as the club threatens to destroy itself from the inside out.
