A documentary examining why genocides keep occurring--from the Armenian genocide in 1915, to the Holocaust, Bosnia, Rwanda and now Darfur. With the contribution of the band 'System of a Down', whose members are all grandchildren of genocide survivors, the film traces the locations and stories of genocide in the last century. Through the arguments of Pulitzer prize-winning author Samantha Power, the personal stories of genocide survivors, policy critics and whistleblowers--the "screamers"--the film dissects the problem of genocide denial and, as well, Power's thesis that America's interest has always been to stay neutral, no matter how wide-scale the carnage, with successive Presidents conspiring to turn a blind eye to genocides as they are happening. After the Holocaust, we may say "never again"--but we don't mean it.
