Dark sci-fi feature from the Spierig brothers. A nameless time travelling agent (Ethan Hawke), hunts down future would-be killers to prevent their crimes from ever taking place. But in his last mission, the agent must try and find the one criminal who has always eluded him through the depths of time, a man known as The Fizzle Bomber. Meanwhile, before his retirement, his employer (Noah Taylor) also instructs him to train a new female recruit, The Unmarried Mother (Sarah Snook), who is now living as a man. As the traveller pursues the criminal and tries to prevent his planned attack of New York, he finds out some startling revelations about his own mysterious background.
