So as the Sons let the shock of Donna’s death (and for Clay & Trig, their mistake which led them to kill an innocent woman who is also the wife of a loyal brother) Clay sets up a new gun deal with the IRA. Meanwhile, a white supremacist group led by cigar king Ethan Zobel (Adam Arkin) takes root in Charming and threatens more than just SAMCRO’s control over Charming. At the party for Bobby’s release from prison, Zobel approached the SOA and let’s his intention be known. We find Gemma, who heading hom, tricked by Zobel’s daughter and knocked out cold. When she comes to she is gagged and ticked to a chain link fence and raped by 3 of Zobel’s men who give her a warning message to Clay. Gemma is traumatized but doesn’t tell Clay; instead she calls Chief Unser who gets Tara to treat Gemma. Tara sneaks Gemma into the hospital without letting staff or the police know about the rape as Gemma wants to save her husband & son the pain she is feeling.Ironically this leads to Gemma becoming more caring for others, especially Tara and the two of them become close confidants.

Meanwhile, a rival porn producer (Tom Arnold) moves to put Luanne out of business; and Clay takes exception to Jax’s hasty decision-making. Jax, seething from the mistrust that led to Donna being killed, acts out and enters a partnership with Luanne in exchange for protection. This will lead to Opie beginning an affair with porn star Lyla, as she sympathizes with him and being a single parent herself.  Zobelle cooks up a “temporary problem” for Hale to solve as a way to undermine SAMCRO; Gemma’s secret is undermining her relationship with Clay; and Jax’s involvement in Luanne’s porn business is getting to Tara. Meanwhile, Clay tells Bobby, who needs a job, to do the bookkeeping at CaraCara, Luanne’s porn studio. Tensions between Jax and Clay escalate when they disagree over strategy for rescuing Tig after he’s captured by bounty hunters on a gun-running mission. Back in Charming, Gemma is rattled by a graphic reminder of her attack, and she sets out to do something about it. Charming and its small-town appeal become vulnerable to The League, which finds new ways to provoke SOA members. Tara’s compassionate efforts to help a distraught Gemma don’t go unpunished. ncited by Zobelle, Clay sets a course for retaliation, forcing Jax to turn to an unlikely source to save the club from destruction. Gemma shows Tara how an old lady handles her anger. With nearly every SAMCRO member behind bars, the club must make new alliances in prison to survive. ATF Agent June Stahl uses this imprisonment to test Clay and Jax’s relationship.

Zobelle’s business dealings with SAMCRO rivals exacerbate divisions in the club, which is already driven 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, Fiona, shows up at his hospital bedside. 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. Agent Stahl takes notice at the handsome profits SAMCRO is reaping. Meanwhile, the Jax-Clay standoff forces Gemma to make a difficult decision. With Tara present she tells both Clay & Jax about the rape. Step-father & son put aside their differences to come together and seek revenge. Chibs contemplates making a secret deal in order to protect his wife and daughter. Deep in emotional turmoil, Opie seeks both revenge and reconciliation. The entire SAMCRO family goes on lockdown inside the clubhouse as Jax and Clay prepare to battle the League. A.J. Weston learns the truth about Ethan Zobelle’s business dealings in Charming. Applying what she has learned from Gemma, Tara ensures her position at St. Thomas Hospital.As SAMCRO attempts to rid Charming of Ethan Zobelle and the League permanently, familiar faces present new challenges. Stahl kills the IRA leader in California Jimmy’s son Eddie but frames it on Gemma who had followed Zobel’s daughter, and Eddie’s lover, to his house. So as Stahl radios the news that Gemma has killed Eddie, Jimmy is furious and steals Jax’s son Able killing Halfsack in the process and tying up Tara.

The Sons are in a race to find Jimmy and get Able back but Jimmy leaves with the baby on board a boat leaving a broken hearted Jax at the pier with the rest of the club standing around in shock.
