Diamond (PRAS MICHEL) is an aspiring rap artist who hopes his music will be a legitimate way for him to escape his inner city life. Unfortunately, his lack of enough money prevents him from getting the quality studio time he needs. Thus, he often accompanies and backs up his best friend and "producer," Gage (JA RULE), on the various drug runs he makes for Mr. B (JASON STATHAM), a local crime lord, to earn extra cash.
Diamond's home life isn't much better than his professional one. His mother has just died, his long estranged, jazz musician father, Cliff (VONDIE CURTIS HALL), is temporarily staying with him, and his girlfriend (TAMALA JONES), has just announced she's pregnant.
Nonetheless, Diamond continues trying to put together a demo tape, but little does he know that Gage - who sees a more luxuriant life for himself through financing his friend and then riding his coattails to success - has made some poor choices in the ways he's been "raising" money for his friend. As a result, Diamond must contend with the ramifications of Gage's criminal behavior, all while dealing with his father and girlfriend as he tries to finish his album.
