The short but bloody career of one of the most infamous outlaws of the 1930s is chronicled in this drama. Charles Arthur Floyd (John Ericson) finds work on an oil rig after serving time for armed robbery, but when he becomes involved with a married woman, her husband swears revenge. Floyd's boss doesn't know that his new employee was a jailbird, and when the cuckolded husband breaks the news, Floyd is out of a job. With nowhere to go, Floyd heads back to his father's home in Oklahoma, but when he learns that a neighboring farmer killed his father, Floyd goes berserk and murders the farmer. Floyd recruits three fellow criminals, Al (Barry Newman), Baker (Philip Kenneally), and Curly (Carl York), and together they cut a swath through the nation, robbing banks and leaving bodies in their wake. A young Peter Falk appears in a minor role, as does Al Lewis, who later gained fame as Grandpa on the TV series The Munsters.
