SOA gathers the tribe for protection, preparing for the showdown with Zobelle and Weston. The club gets revenge on Weston, Agent Stahl and the IRA. Gemma and Tara talk religion, Tara gets her job back using her connections to the club. Tensions mount between Chief Unser and Deputy Chief Hale.

The rest of the club finds out what happened to Gemma and plot their revenge on Zobelle and Weston. Opie learns the truth about Donna’s murder from Tig and the club deals with the fallout. Opie goes after Agent Stahl for her role in Donna’s death. Jax learns somethings about Zobelle and LOAN. Chibbs comes clean with the club about his dealings with Agent Stahl.

Agent Stahl takes notice at the handsome profits SAMCRO is reaping from the repo business. Meanwhile, the Jax-Clay standoff forces Gemma to make a difficult decision. This will be a 90 minute episode according to Kurt Sutter’s Twitter message.

When SAMCRO’s adult-film business becomes a hindrance to the club, Clay seizes the opportunity to revive the gun-running cartel. As Jax and Clay continue to clash over club activities, their relationship reaches a new level of antagonism

Zobelle’s business dealings with SAMCRO rivals exacerbate divisions in the club, which is already riven by the Jax-Clay split. And complicating matters further, Georgie Caruso’s thugs attack Luanne’s studio. Meanwhile, Clay comes to an agreement with Elliott Oswald (Patrick St. Esprit); and Chibs’ estranged wife shows up at his hospital bedside.

Since The League has SAMCRO members behind bars, the club must make new alliances in prison to survive. Alcohol, Tobacco and Firearms Agent Stahl uses this imprisonment to test Clay and Jax’s relationship.
