America has been stuck by a glut of serial killers over the years, but the phenomenon began with the work of one man: H.H. Holmes. Based in Chicago, Holmes terrorized the local community with a series of murders and his infamous "death house." A local landlord, Holmes ensnared his victims by renting rooms to them during the World's Fair in 1893. The house was littered with torture chambers and evil tools with which Holmes carried out his deeds. Filmmaker John Borowski has meticulously researched the case, and produced this chilling documentary on Holmes. Revisiting some of the mass murderers past haunts, Borowski draws on photographs, reenactments, and location footage to relive the ghoulish tale.
