Hanna (Saoirse Ronan) is a teenage girl. Uniquely, she has the strength, the stamina, and the skills of a soldier. These come from being raised by her father, Erik Heller (Eric Bana), an ex-C.I.A. man, in the wilds of Finland. Living a life unlike any other teenager, her upbringing and training have been one and the same, all geared to making her the perfect assassin. The turning point in her adolescence is a sharp one; sent into the world by her father on a mission, Hanna journeys stealthily across Europe while eluding agents dispatched after her by ruthless intelligence operative, Marissa Wiegler (Cate Blanchett), who has secrets of her own. As she nears her ultimate target, Hanna faces startling revelations about her existence and unexpected questions about her humanity. Written by Focus Features
