Build a movie plot around this: What reunited the four brothers? Evelyn's murder
Answer:
The seemingly random murder of their adoptive mother, Evelyn Mercer (Fionnula Flanagan), at a Highland Park, Michigan convenience store, brings four brothers back home to Detroit, Michigan to find out what happened. Originally under the impression the crime was a simple robbery-gone-wrong, the brothers soon discover that the robbery was merely a cover for what was, in fact, a hit put out on Evelyn. After this revelation, Bobby (Mark Wahlberg), Angel (Tyrese Gibson), Jeremiah (Andre 3000) and Jack Mercer (Garrett Hedlund) track down the hired guns who killed Evelyn. Refusing to say anything, they are unceremoniously executed by Bobby and Angel.The next day, Detroit Police Lieutenant Green (Terrence Howard) and Detective Fowler (Josh Charles) confront the brothers about the murders. Lieutenant Green warns them that their interference with Evelyn's case is ill-advised, and that it will eventually put them in over their heads. After confronting Jeremiah about the revelation of his failing business and benefiting from Evelyn's life insurance, the brothers are treated to a somewhat different version of events. Jeremiah informs them that his construction company was failing precisely because he was not getting involved with Victor Sweet (Chiwetel Ejiofor), and that for a project to succeed he had to pay off the right people, which he initially failed to do. In his effort to restore his business and relieve pressure from himself, he tried to pay off Sweet's henchmen. As for the life insurance, Jeremiah explains that the money went directly to him for his daughters, because he paid all of Evelyn's bills while his other brothers were not around.Back at their home, during a confrontation with Jeremiah, Sweet's men attack the brothers. Jack is shot and killed during the attack. Bobby finds one of the gunmen still alive and questions him about who sent them. He almost spares the gunman but is offended when the gunman mumbles "Thank God" and kills him anyway. When Lieutenant Green arrives, he tells them not to worry...
