Originally with a straightforward plot about a homicidal sniper acting alone and a SWAT team hunting him down, the network-TV version adds 30 minutes of side story, making the sniper a hired hand for a band of robbers, acting as a cover-up for an art heist. This version was conceived during negotiations between Universal Pictures and NBC in 1978, because NBC refused to air a film centered around a homicidal sniper. This version is sometimes aired on broadcast TV in the USA. In this version, the copyright and legal information titles are left out!
