South Los Angeles has been divided by the Crips and the Bloods since the late 1960s, and Stacy Peralta traces how two gangs formed in the same neighborhoods within a few years of each other, then spent decades at war. Peralta interviews current and former members alongside gang-intervention workers, academics, and activists including Jim Brown and Kershaun Scott, building a street-level account of how territory, guns, and family breakdown structure daily life in these neighborhoods. The film pushes past the violence itself to ask what produced it: the disappearance of industrial jobs from South LA, the removal of Black fathers through mass incarceration, and a statistic the film returns to directly, that one in four Black men will serve time in prison. Ex-members describe what pulled them in and what it cost them, giving the history behind the two names a human scale rather than a headline. Peralta, better known for skateboarding documentaries, treats the gangs as a symptom of abandoned neighborhoods rather than a simple crime story.
