Miguel goes into business with a shady new doc who wants to amp up Cadena's supplies, just as Chato gets into bed with a lady (Maria Conchito Alonso) with dangerous family ties. Meanwhile, Marlene's dirty little secret comes out in time to put half her family in joepardy; and Klein turns to a less-than-reliable source to improve his tragically compromised finances.

Tensions heighten between traffickers and law enforcers as a major bust is about to go down; the brutalization of Chato comes back to haunt the corrupt Lazarenos.

Kingpin ends on a quiet moment, with Miguel accepting Chato back into his life, but opens with a bang as Delia goes against Doug Duffy's orders and ends up saving Undercover Bobby's life during the raid on Truck's club. Dr. Benben tries out a professional bodyguard, but ends up pairing up with Junie. Things with La Corporacion are kind of a mess, but everything works out for the best after Miguel pays the CIA $20 million and the Senator is strangled by a bolo tie. Yes, a bolo tie.

As Miguel is warned by Lupita, who forsees of a black cloud looming over his impending deal with a Thai heroin cartel; Delia is crushed after she's transferred out of El Paso. Klein's ex-wife (Sean Young) comes back with a high-priced demand that forces the doctor to take drastic action.

Ernesto's ""murder"" puts Miguel in control of the cartel and at odds with a pair of associates opposed to his new role. Meanwhile, Klein turns to a client (Darius McCrary) for help in getting out of the trade; and Delia steps up her plan to avenge her partner's murder. Lupita: Elpidia Carrillo. Manny: Danny Trejo. Tio Beto: Miguel Sandoval. Marlene: Sheryl Lee.
