The second season ends with SAMCRO trying to get rid of Ethan Zobelle (Adam Arkin) and his cohorts once and for all.

Jax and Clay keep SAMCRO focused on their impending showdown with Zobelle's group; thanks to Gemma, Tara improves her job security at the hospital; Weston finally discovers his boss's intentions in Charming.

While Opie seeks both revenge and reconciliation, Chibs makes a secret deal with Agent Stahl (Ally Walker) to protect his wife and daughter.

Agent Stahl (Ally Walker) 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.

With the porn business becoming more trouble than it's worth, Clay pushes for a greater emphasis on gunrunning. Meanwhile, the Clay-Jax schism grows even wider.

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.

To help SAMCRO out of its predicament, Gemma goes to Elliott Oswald (Patrick St. Esprit) to call in a favor, and Opie runs an errand for Clay. Meanwhile, Agent Stahl, who has an agenda of her own, offers Clay and Jax separate propositions; Bobby lays it on the line for Jax; and Gemma and Tara have a tense encounter with Lyla (Winter Ave Zoli).

Clay plots retaliation against Zobelle, forcing Jax far afield in his effort to head off Clay. Meanwhile, Gemma gives Tara a lesson in anger management.

While Jax and Clay lock horns (and line up support) over how to deal with Zobelle, Tara finds herself ensnared in Gemma's emotional struggle in the aftermath of her attack. Meanwhile, SAMCRO gets help from an unlikely source.

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.

Zobelle (Adam Arkin) cooks up a "temporary problem" for Hale to solve as a way to undermine SAMCRO; Gemma's rape 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 run the business end of Luanne's business.

Following a traumatic event, Gemma finds herself unable to tell either Clay or Jax about it. Meanwhile, a rival porn producer (Tom Arnold) moves to put Luanne out of business; and Clay takes exception to Jax's hasty decision making.

As Season 2 opens, SAMCRO must deal with internal repercussions from the murder of Opie's wife. Meanwhile, a surprisingly sophisticated white supremacist named Ethan Zobelle (Adam Arkin) arrives in Charming to open a tobacco shop. Both Zobelle and his less-sophisticated associate (Henry Rollins) are determined to take down SAMCRO because of its dealings with black and Latino bikers. Stahl: Ally Walker. Darby: Mitch Pileggi.
