In April 2001, a house explosion in Scottsdale, Arizona leads police to the bodies of Mary Fisher and her two children, killed before the blast, and to a manhunt for her husband Robert Fisher that has never officially ended. The film retraces the case through investigators, neighbors, and family members who describe the man before the crime, a respiratory therapist with no criminal record, and the evidence that turned him into one of the FBI's most wanted fugitives. It follows the tips that poured in for years, from sightings in national parks to claims he joined a monastery or died by suicide in the wilderness, and the searchers who kept combing the Arizona backcountry long after the trail went cold. Rather than settling on a single theory, the documentary lays out competing possibilities and lets the unresolved timeline speak for itself. Two decades on, Fisher's case remains open, and the film closes with the same question that has driven the search since 2001: is he alive, and where.
