A mysterious loner assumes the responsibility of protecting a newborn from a group of men determined to kill the child in first-time director/screenwriter Michael Davis' nonstop, adrenaline-fueled action film. Mr. Smith (Clive Owen) is the last man that a parent would want to have looking after their child, yet after stumbling upon a blazing shoot-out, helping to birth a child amidst a hail of gunfire, and seeing the mother die before his eyes, he becomes determined to protect the young innocent at all costs. But his adversaries are equally determined, and they will not stop until the newborn is dead. Now, in order to ensure that maniacal criminal mastermind Mr. Hertz (Paul Giamatti) and his gang of henchmen do not succeed in accomplishing their nefarious goal, Mr. Smith joins forces with a prostitute known as the Dairy Queen (Monica Bellucci), who specializes in lactation fetishes, and flees into the bowels of the city while facing almost certain death on every street corner.
