Season Two of Gangland Undercover picks up Charles Falco’s story as he seeks refuge from the aftermath of Operation 22 Green against the Vagos. Almost a year on from the busts, he is living a strange new life as a man with no identity in an unfamiliar Virginian town. He’s desperately trying to fit in, but fueled by a restless unease and an inability to embrace his new world, he finds himself agreeing to sign up to a new undercover operation, this time against the Mongol bike gang. Before he knows it, he’s in over his head, and plunged into a world darker and more dangerous than anything he experienced in the Vagos…
Introducing us to a raft of colorful new characters (and the surprise return of some old ones), this new season sees Falco’s wits tested to the limits as he joins ranks with Bullet: a grizzled, relentlessly driven undercover cop with a personal grudge against bike gangs…
Together, they recruit a team of confidential informants to infiltrate not just the Mongols, but one of the most notoriously violent biker gangs out there: the Outlaws.
But as ever, Falco’s personal life makes for complications, this time in the form of the seductive, free-spirited artist Sarah-Jane. Falco is taken by surprise to discover she is a devout Christian, and soon finds himself drawn into the world of her church, where there is no hiding from his personal inner demons. When she falls pregnant out of wedlock just as the operation goes into overdrive, Falco is caught in a precarious web of lies and deceit from which he can see no escape…
As he navigates his way through faked murders, armed confrontations, misjudged drug deals and gunpoint polygraph examinations, the season culminates with a massive, Fourth of July Outlaw rally at which Falco finally earns his patch, setting the table for a potential Season Three in which Falco’s earlier mistakes come back to haunt him as he goes ever deeper into his infiltration...
