At California's San Quentin State Prison, baseball is played as a way to teach life lessons. Members of the Tri-Valley All-Stars, a recreational team that enters the prison to play against the inmates, share their stories, and inmates tell how baseball has helped them deal with their problems. The prison chaplain, a former gang member, discusses the challenges of managing an all-inmate team. And former major league All-Star Ron LeFlore, who was drafted by the Detroit Tigers while serving a 15-year sentence for armed robbery in Michigan State Prison, reflects on how baseball helped him reform.
