SOA plans revenge on a rival biker club while hosting the wounded Cameron Hayes in the clubhouse. Meanwhile, Jax, Bobby, and Opie strive to clear the gun debt forever.

The entire SAMCRO family goes on lockdown inside the clubhouse as war with the League approaches. Opie decides not to pursue revenge against Clay or Tig for Donna's death. Jimmy puts an end to Cameron's deal with Zobelle, agreeing instead to sell exclusively to SAMCRO. As Chibs backs out of the deal with Stahl and attempts to convince Fiona to let him protect her, Clay tells Jimmy that Edmond has flipped. After Jax witnesses Zobelle meeting Álvarez, SAMCRO inform Weston of the real nature of Zobelle's business dealings. Tara applies the lessons she has learned from Gemma to assert her position at St. Thomas. SAMCRO approach Laroy and Lin about uniting against their common enemies; the League and the Mayans. Edmond re-negotiates his deal with Stahl, seeking immunity for himself and Cameron. Hale makes a decision about what kind of chief he wants to be.
