She must befriend the daughter of a key scientist to gain access to the blueprints for a bomb that could destroy the cities of Western Europe, and steal them.

She's a brilliant con artist, convincing them she's one of them even as she lives in terror of being found out. And she's determined to get her revenge on them all.
