Shoot 'Em Up (2007)

A man named Mr. Smith delivers a woman's baby during a shootout, and is then called upon to protect the newborn from the army of gunmen. - Anonymous

Late at night, in an unnamed U.S. city, a solitary man sits at a bus stop. A pregnant woman runs by, pursued by a man with a gun. With reluctance, the man at the bus stop rescues her and assists with the baby's delivery, while additional pursuers fire at them, including the gang's particularly nasty leader, an intuitive man named Hertz. Our hero, known only as Smith, determines to save the child and find out why Hertz wants the baby dead. At a local bordello, he tries to employ a lactating hooker to watch the child, but things quickly escalate, and this makeshift family is soon on the run. Heavy metal music calms the baby. Why? A laboratory, gun factory, and presidential campaign all figure in Smith's quest for the child's safe deliverance.

In the middle of the night, while waiting for a bus in a bus station, a lonely stranger called Mr. Smith sees a pregnant woman being chased by a man with a gun. He follows the couple, kills the man and helps the delivery of the baby in the middle of a shootout while a gang of hit-man tries to shoot them up. The woman is killed but Smith saves the baby, escaping from Hertz, the leader of the killers. Then he meets the prostitute Donna Quintano, who has just lost her baby, and asks her to breastfeed the newborn. They are chased by Hertz and Smith discovers the reason why the bad guy wants to kill the baby. - Claudio Carvalho, Rio de Janeiro, Brazil
