TAS: Saoirse Ronan plays the title character. She lives in the remote, snowy wilds of Finland with her ex-CIA agent father Erik (Eric Bana). He has taught her survival skills, in addition to weaponry and martial arts. She can speak multiple languages fluently. It gradually becomes clear that he's training her to defend herself against a CIA operative named Marissa Wiegler (Cate Blanchett), who patiently waits for the day that Erik and Hanna resurface from their exile.
