As Bea and Twila begin their training, Bea becomes the handler for Soviet technician Sasha and catches the eye of the dangerous KGB officer Andrei; Twila's assignment‬ ‭entertaining a businessman uncovers a much deeper conspiracy.

Bea strengthens her cover on a date with Andrei; Twila dives into an off-the-books investigation of‬ ‭a string of sex worker murders.

Twila runs her first asset, Vera, a Russian fixer with secrets tied to their husbands' deaths; as‬‭ Bea's bond with Sasha grows, so does the danger.

In a bold move, Bea enlists an unlikely ally to pose as Vera, but what seems like a victory may actually be a trap.
