 England 1945: Working late, an arrogant textile scientist assures the failing factory s owner, Gregory Spain, he ll soon perfect his long-promised miracle fabric. After the owner heads home, the scientist urges a homeless man he just hired on to sweep out his lab, to try on one of the scientist s own suits, then knocks the janitor out and blows up the factory with a bomb. After serving 14 years for insurance fraud and for murdering the scientist, the factory owner traces the scientist, who framed him, to the U.S., where Spain hires Peter Gunn to flush his quarry out into his gun-sights.
