Four Brothers is a 2005 action movie directed by John Singleton. It is a modern adaptation of the 1965 Western entitled The Sons of Katie Elder. After Evelyn Mercer (Fionnula Flanagan) is murdered during a convenience store robbery, her four adopted sons, Bobby (Mark Wahlberg), Angel (Tyrese Gibson), Jeremiah (Andr'' Benjamin) and Jack (Garrett Hedlund), come back home to Detroit, Michigan to attend her funeral. Although the police tell the men that it was just a random killing, the brothers soon learn information that makes them suspect it might have been a hired hit. Determined to bring their mother's murderers to justice, the enraged men try to track down everyone involved in the crime in order to enact their vigilante justice. But as they learn more about the circumstances surrounding their mother's death, they are unnerved to learn that their mother may have been killed due to the criminal involvement of one of the brothers.
