When the Mayans, a Latino gang led by Marcus Alvarez, steal the Sons' stockpile of weapons and burn their warehouse, SAMCRO is placed in a difficult position, as they have already taken payment for the guns from the 1-9ers, a powerful African-American gang led by Laroy Wayne. As Clay plots their revenge, Jax finds an old document written by his dead father, co-founder of the Sons, about the direction in which he wanted SAMCRO to go; nothing like the gun-running direction in which Clay has taken them. When they locate where the Mayans are hiding their weaponry, Clay calls upon Jax to bring his friend Opie back into the fold. However, Opie has recently been released from jail after refusing to testify against SAMCRO, and has promised his wife Donna he will go straight. Meanwhile, Jax's estranged-wife, Wendy, takes a drug overdose, leading to an emergency C-section and life-threatening surgery for her and Jax's son, who is ten weeks premature. Complicating matters is that the case is being handled by Dr. Tara Knowles, Jax's childhood sweetheart, who has returned to Charming after ten years away.
A rival gang steals the Sons' stockpile of assault rifles, while Jax's ex-wife's drug overdose leads to an emergency c-section and life-threatening surgery for their baby.

It changes to morning and the Sons of Anarchy arrive at a burnt out warehouse. A police officer and fireman are paid to cover up the investigation.

At the garage (owned by the Sons of Anarchy) a prospect is charged with getting a moose out of the car. Jackson receives a phone call from his mother Gemma (Katey Segal). The rapport is cheeky but lovely and she clearly has a hand in the operation of a club. Jackson asks his mother to check in on his ex-wife Wendy.

At Gemma's house the audience learns that Gemma is now married to club president Clay Morrow. Gemma tells Clay that Jackson has been thinking about his dead father.

At the hospital Tara tells Gemma that Able needs his second surgery. She also asks Gemma to look in on Wendy. When Gemma refuses, Tara asks Gemma if she has a problem with her assisting in the surgeries. Gemma denies this but ten years of Tara being away has not mended any bridges and their altercation borderlines on the physical side.
At Opie's house, his wife Donna (Sprague Grayden) is verging on hysteria when she guesses correctly that Opie may be doing another job for the club. He has only recently got out of prison. Jackson sees part of the altercation and tells Opie to take his child to the hospital as an alibi for Clay and for not doing the job.
