South Central, Los Angeles. For many, the words evoke images of fear and violence. For Malik Spellman, these words suggest hope. A violence prevention counselor by day, Spellman tours the streets of his hometown at night, on a mission to bring peace to the troubled neighborhoods he's lived in for 30 years. For the last two decades he's dedicated his life to ending gang violence, putting it all on the line to mediate truces between rival gangs in Los Angeles -- adversaries sometimes separated by less than one city block. Each episode of "The Peacemaker" provides an unprecedented look at gang life, following Spellman as he coordinates and oversees tense moments of mediation between enemies with long histories of hate and violence.
