From the genesis of LA's gang culture to the shocking, war-zone reality of daily life in the South L.A., the film chronicles the rise of the Crips and Bloods, tracing the origins of their bloody four-decade-long feud.

Contemporary and former gang members offer their street-level testimony that provides the film with a stark portrait of modern-day gang life: the turf wars and territorialism, the inter-gang hierarchy and family structure, the rules of behavior, the culture of guns, death and dishonor.
