Running Scared (2006)

The gangster Joey Gazelle is in charge of getting rid of the guns that killed dirty cops in a transaction of drugs between Italian mobsters and Afro-Americans. However, Joey hides the guns in the basement of his house instead of throwing in the river, and his ten years old son Nicky and his best friend Oleg Yugorsky witness Joey hiding the gun. When Oleg's abusive stepfather Anzor Yugorsky beats his mother Mila, Oleg steals the weapon from the basement and shoots Anzor, running away home with the gun. Along the night, Joey, the Russian and the Italian mobster and the dirty cops chase the little boy trying to retrieve the gun and disclose who ordered the boy to shoot his stepfather.
