The Act of Killing depicts a group of unrepentant former members of Indonesian death squads being challenged to re-enact some of their many murders in the style of the American movies they love. The film focuses particularly on one individual, Anwar Congo, whose initial enthusiasm for the re-enactments slowly gives way to outward expressions of unease and remorse.
