When race car driver, Brewster Baker, stops at a gas station, parts are stolen from his race car. Then while in a diner in a small Texas town, he sees some people stealing parts from another car, and chases the thieves. When the thieves' van goes into a river, Brewster rescues them and discovers that they are orphaned children. The kids were stealing auto parts for "Big John" the corrupt county sheriff, who jails Brewster for breaking and entering, larceny, resisting arrest and speeding.
