It is 1974 and life is not easy for a black male to find employment, even college-educated Jim Ellis (sports) (Terrence Howard). While struggling to find anything better, Jim, a former competitive swimmer, is working on the decrepit Marcus Foster Recreation Center operated by the Philadelphia Department of Recreation. The center includes a dilapidated swimming pool, which Ellis rehabilitates. Ellis's presence and activities cause friction with a bitter, overprotective janitor named Elston (Bernie Mac). One day, Jim invites a group of black teens who have just been thrown off the basketball court in the Center's yard in for a swim. Andre (Kevin Phillips (actor)), Hakim (Nate Parker), Reggie (Evan Ross), Puddin’ Head (Brandon Fobbs), and Walt (Alphonso McAuley) prove to be fairly capable swimmers and with a few pointers, could become great swimmers. With some help from Elston, Jim decides to try to save the swimming pool by starting the city's first all African-American swim team, the P.D.R. team (Pride, Determination, Resilience). When the team acquires Willie (Regine Nehy), a female swimmer more talented than any of the boys, the prospects of competing against much more experienced white teams begin to improve. Jim also develops a romantic interest in a beautiful city councilor (Kimberly Elise), Hakim's sister and guardian. Throughout their struggles in and out of the swimming pool, Jim and Elston encourage and mentor the kids, helping them not only to become successful at swimming but also in their struggles against prejudice, crime, and poverty.
