A story of killers who win and the society they build.

After befriending documentarian Joshua Oppenheimer, former Indonesian death squad leaders reenact their real-life mass killings in the style of various American film genres. As they recreate their past atrocities, the line between reality and performance blurs, exposing the lingering impact of Indonesia's 1965-66 anti-communist purge and the unsettling psychology of its perpetrators.
