Haunted by his inability to locate Job following his abduction from Camp Genoa two years earlier, Lucas returns to Banshee to find the town dramatically changed - with a new sheriff, a new mayor, and a serial murderer on the loose.

With her hunt for Job yielding no leads, Carrie vents her frustration by embarking on a vigilante crusade against members of the Brotherhood. Lucas beats Brock and Bunker to a person of interest in the serial murder case, but ends up finding himself under suspicion.

With new intel from Fat Au, Lucas and Carrie follow a Genoa lead in a last-ditch attempt to free Job, though the price is steep. Proctor finds that generosity sometimes goes unrewarded, while Lucas pays the price for rescuing Rebecca from Boedicker.

Agent Veronica Dawson arrives in Banshee to investigate the serial murders and to question Lucas, already under fire from Brock about his relationship with Rebecca. Carrie carries out her most ambitious strike yet against the Brotherhood. Another murder rocks Banshee.

Calvin is tested by Watts' mercenary partnership with Proctor, whose promise to the Colombians has taken a severe hit after the torching of his factory. Following separate leads in the serial-killer case, Dawson and Lucas converge in a members-only Goth club.

With help from Lucas, Dawson narrows her search for Declan Bode, a Satanist "person of interest" in Banshee's serial murders. An emboldened Calvin throws down a gauntlet to Proctor, and to Kurt. Carrie's recent vigilantism ends up putting both her and Deva in peril.

Fearing for Dawson's safety, Lucas and Brock ramp up their efforts to hunt down Bode. With the Brotherhood poised to go to war with Proctor, Kurt looks to keep Maggie safe while Calvin takes out his frustrations at the office. Job settles a score with Leo Fitzpatrick.

Lucas learns the murder case he thought was finally closed may in fact be reopening. Proctor looks to finalise his deal with the Colombians. Carrie takes aim at one final act of vengeance. Brock demands allegiance from Bunker as Banshee braces for an uncertain future.
