Gabriel Adams witnesses a stripper's death when an argument between two sex traffickers spills out into the main club lounge. After his relocation to New Mexico, Gabe eagerly accepts his new role as a bartender. But the more that Mary checks on the priest while leading up to his federal case, the more she finds out about his immoral past.
Meanwhile, Stan must confront the daughter of a witness, Roy Keels, who has died under protection. She comes to find out more about her father, and after lying to her about his character, she finds out that he was nothing but a "petty" criminal.
Mary's personal life is shaken up when Brandi and Peter announce that they're moving in together. And Marshall and Jinx pressure her to use her vacation days before they expire under new WitSec rules.
