Crime boss Jimmy Reardon continues his informer-role with Organized Crime Unit Director Mary Spalding, at the same time shipping his own grower-turned-snitch, Bill, off to Mexico. Mary is still being groomed for a position at CSIS, though pressure is mounting to prove Reardon's value as an informer. Reardon tips Mary off that one of her wire-room operators is actually a mole working for the Chinese Triads, hoping in return Mary can help him in his custody battle with his ex-wife Francine. But with a mole in her wire room, the future of Mary's whole unit is now in jeopardy. And it doesn't help either Mary or Reardon when Bill suddenly turns up dead. Mary's Deputy-Director, Ted Altman, is pleased, wanting to undermine Mary as much as possible. Reardon denies involvement, but his own suspicions point to his impulsive brother, Michael.

Michael is behind the hit on Bill, but can't afford to pay for it, so he accepts a dope run with the bikers for cash. Ted, hoping to dig up dirt on Bill's murder, puts surveillance on Michael. Mary, in order to placate superiors about Reardon, offers to get an undercover operator inside Reardon's operation. She recruits Tina, a stripper, who gets a job inside Reardon's strip-club, "The Chickadee." Meanwhile, Mary's wire room finds out about an arms shipment to Africa that is tied to a local broker, Bingham. Reardon finds out about Michael's debt for the hit, and pays it off to smooth things over. Mary uses Reardon's connection to Bingham to scare him into thinking the police know about his shipment. Mary's wire room picks up more info as a panicked Bingham calls his connections. Michael finds out about the surveillance on him and is able to evade it.

Reardon has his ATMs ready to start laundering cash. Now that Michael is a hero for stopping the hitman, he's put in charge of security for the cash runs. Tina, the stripper-informer, is getting cozy with Reardon's banker, Hogarty. Mary's freelancer, Forrest, has begun surveillance on the mole, Lee. Lee has a girlfriend who is talking about getting her brother to kill Lee's wife. Ted tells Deakins the DEA are on board for a reverse sting to bring Reardon down. Deakins doesn't have time for a lengthy sting, he needs dirt on Mary now. Ted looks into setting up a wire in Mary's apartment. Mary learns the brother of Lee's girlfriend is a leader in the local Hong-Kong backed gang, the Red Eagles. Bingham approaches Reardon and asks if his shipping connections can help with a gun-shipment. Reardon passes the info on to Mary in exchange for information on his would-be assassin.

Mary prepares a sting operation on Lee. Reardon wants to see his daughter Stella, but Francine is still in the way. Ted meets with his DEA contact, Williams, and agrees to hand over all his intelligence files on Reardon -- but only if he gets to meet Williams' undercover operator. Bingham offers Reardon a stock offering in exchange for moving the gun shipment and Mary asks him to accept the deal. She also informs Reardon his would-be assassin is connected to the Vietnamese. Reardon meets with his Vietnamese contact, Phan, who promises to take care of his disgruntled former supplier. The sting on Lee goes off and Mary interrogates him. He agrees to turn on the Red Eagles and work for her. Stella sneaks away from home and shows up at the strip club looking for Reardon. Francine calls, enraged, but Reardon is able to get her to agree to let Stella stay the night with him.
