John Jairo Velasquez, known across Colombia as "Popeye," spent the 1980s as one of Pablo Escobar's top enforcers, and today strangers stop him on the street for selfies. The film follows him through that strange celebrity, tracing his years arranging assassinations for the Medellin cartel, including the shooting of policemen and bombings targeting politicians and government officials. Velasquez claims to have personally killed over 250 people and arranged the deaths of thousands more; on camera he recounts the killings with a flat, sometimes wistful detachment, at one point saying "I feel like my soul is dead." After serving 23 years in prison, he emerges to write two books about his time with Escobar, dabble in film production, and give interviews to people eager for a piece of his notoriety. The film sets his account against interviews with his victims, who describe what his violence actually cost them, and lets the contrast between his fame and their loss sit unresolved rather than resolving it for the viewer.
