The flurry of characters takes a long time to get straight, and identification is made even harder by the nervous handheld camerawork and rapid-fire editing that makes no concessions. But no matter: the film comes into its element in the imaginative action scenes.
Bloody revenge is at the heart of this stylish, kinetic action-thriller that gives a welcome shot of adrenaline to the classic femme fatale story. Honed from childhood into a merciless killing machine by a criminal organization, assassin Sook-hee is recruited as a sleeper agent with the promise of freedom after ten years of service - and she jumps at the chance for a normal life. But soon enough, secrets from her past destroy everything she’s worked for, and now nobody can stand in her way as she embarks on a roaring rampage of revenge.
