Briggs and Charlie slip back into former aliases for a meet with a mid level heroin dealer who has connections to a major trafficker known as Odin Rossi, but when Whistler makes a surprise appearance the agents worry that their cover may be compromised. The only way to be sure will be for Charlie to pay a visit to her former CI, but using Whistler leaves her with a guilty conscience.

Cornered by Mike at a Narcotics Anonymous meeting, Briggs gives the young rookie the whole truth: as a young agent, Briggs was kidnapped by the Kaza cartel and turned into a heroin junkie before being set free. It's a massive revelation, one that could have devastating consequences not just for Briggs, but also for Graceland and the entire department.
