Charles Falco manages to infiltrate the notorious Vagos biker gang. But just as he's learning the ropes, a surprise invitation puts the nervous new hang-around squarely in the line of fire.

Now a full-patch Vago, Falco is secretly enjoying his new role as an outlaw biker. When an early-morning police raid goes bust, however, he faces serious allegations on two fronts. Chapter president Schizo is on the hunt for a snitch, and during the gang’s annual Reno run, Darko, the chapter’s sergeant-at-arms, and Stash go rogue forcing Falco to join them on an ill-fated payback operation.

When Stash murders a drug dealer, the D.A.'s determination to convict him threatens to blow Falco's cover. Meanwhile, Falco proves he's a critical asset to both the Vagos and the cops. But when he later throws the first punch in a bar brawl, Falco, Schizo, and Stash all find themselves behind bars on charges of attempted murder.

Facing a month behind bars, Falco quickly moves up the ranks of the Aryan brotherhood; Back at home, uncomfortable questions reemerge and the gang's leadership is thrown by a secret power play at gunpoint.

With Falco's mission almost over, Agent Koz wants Falco to lay low until the bust goes down; Darko and Stash push him to defect and start cooking drugs for their rival chapter, while, Suzanna walks out on him for good.
