Synopsis
The story begins with a woman having a baby during a shootout. The mysterious man who delivers the baby, called simply Mr. Smith (Clive Owen), is entrusted with protecting it from an army of gunmen, after its mother is killed. He thinks the assassins (led by Paul Giamatti) were after the mother, but he soon discovers the baby is the target. Mr. Smith must uncover the reason why this newborn is the target to save the kid's life and his own. But Mr. Smith is the least person who should take care of a baby. He is homeless and angry. He takes the baby to a prostitute named DQ (played by Monica Belluci) and she offers him help.
