The film is a companion piece to the 2012 documentary The Act of Killing
Adi Rukun, a middle-aged Indonesian optometrist, has lived his whole life in an environment shaped by the unending grief his parents feel over the brutal murder of his older brother in the 1965 Indonesian Communist Purge, which occurred two years before Adi's birth. He watches extra footage from Oppenheimer's The Act of Killing project, which includes video of the men who killed his brother, and decides to visit and interview some of the killers and their collaborators—which turn out to include his uncle—while testing their eyesight. Although none of the killers expresses any remorse, the daughter of one of them is clearly shaken when she hears, apparently for the first time, the details of the killings. Interspersed between the confrontations are scenes of Adi's elderly mother and almost deaf and blind father.
