This documentary explores the elusive Zodiac Killer through the lens of filmmaker Charlie Shackleton, who aimed to create an in-depth true crime film. The project involved interviews and footage of California locations associated with the case but was ultimately abandoned, leaving behind fragments and reflection. The film deconstructs storytelling conventions in the genre, blending wit and insight to examine our obsession with serial killers and the stories we craft around them. It is a thoughtful exploration of true crime filmmaking.
