After getting sloppy on her job due to her anger over Antonio's death, Jonas sends Jamie on a vacation at a retreat in Montana. Jamie brings sister Becca along. Just as she's settling in, Jonas calls Jamie to assign her to keep an eye on an assassin who has orders from him to kill a spy that's selling secrets to North Korea. When Jamie finds the assassin dead from a drug overdose, she now insists on the job which falls into her lap when that spy turns out to be the father of a boy Becca just met at the retreat. Back at Burket Group headquarters, Nathan asks Jae to teach him how to fight hand-to-hand to improve his self-esteem.
