Violet (Alexis Bledel) and Daisy (Saoirse Ronan) are a pair of gum-cracking teenage assassins who casually snuff out crime figures in New York City, distracted only by the fact that a concert by their favourite pop idol Barbie Sunday has suddenly been cancelled. Determined to raise cash for a pair of Barbie Sunday dresses, the duo take on a new hit job, only to face a reckoning in the form of a mysterious loner (James Gandolfini). He catapults the hit-girls into an odyssey far beyond the world of Barbie Sunday and bullets for pay. From screenwriter Geoffrey Fletcher (Precious), teenage kicks match wits with adult-world turmoil, as three lost souls face their most formidable foes - themselves.
