Once the fastest-growing motorcycle club in San Diego, the Laffing Devils now must fight for survival. After Prez Billy the Kid goes AWOL, a battle for leadership emerges among the Devils.

The war continues between The Laffing Devils and Sinister Mob. Before Sinister Mob President can plan the next attack, he must gain approval from the more powerful clubs in the community.

Sinister Mob has made the latest move in their war with rival club The Laffing Devils — by destroying a Devil's bike. The Devils fight back in a dangerous race against Sinister Mob.

The Devils face chaos and defeat in a war against Sin Mob. Hoping to save the club, Devil Danny Boy asks former Prez Billy the Kid to return. Later, a violent face-off erupts at the Devils clubhouse that will prove who's actually winning the war.

The Devils and The Mob do whatever it takes to clean up and strengthen their armies. The Laffing Devils' election for Prez is just days away while across town Sin Mob has decided the time has come for Prospect Rob to prove himself worthy of a patch.

When two Devils show up at Sin Mob's bar, Rockem tasks Headcase to press Snubz for intel that will bring down The Devils. Meanwhile, at The Devils' clubhouse, Prez Danny wants White Boi to push local drug dealers out with whatever force it takes.

Devil Snubz finds the dirt on Sin Mob that could help Danny Boy finally take down the rival club once and for all. Meanwhile at Sin Mob, sparks fly between the club's leaders after Bubba catches Rockem running a rogue operation.

Snubz's dirt on Sin Mob leads the Devils to strike back, but troubling news about Sandman distracts Danny from preparing for the counterattack. When Sin Mob attacks the Devils at their clubhouse, the war between the two clubs burns fiercely.
