A body found in pieces, mailed to addresses across the United Kingdom, sets off one of the country's strangest murder investigations. The film follows detectives as they try to identify a victim who exists only in fragments, tracing parcels and postmarks back toward the person who sent them. Interviews and case reconstruction lay out how investigators pieced together forensic evidence, victim identification, and the killer's movements, building a profile of a man who seemed to treat the police search as a game. The documentary walks through the timeline of the killing, the disposal method, and the manhunt that followed, showing how a case with almost no intact evidence still produced an arrest and conviction. Rather than dwelling on shock value, the film stays close to the police procedure: what a partial body can and cannot tell investigators, how postal tracing works, and what finally closed the net on the man responsible. It is a straightforward true-crime account of a case built on forensic patience rather than a single dramatic break.
