Highway Patrol

Robert Paige heads the cast as motor patrolman William Rolph, dedicated to smashing up a deadly rivalry between two oil-refinery companies. Oil executive J. W. Brady (Robert Middlemass) plays fair, but his competitor does not, hiring goons and murderers to carry out the dirty work. Making Rolph's life easier is the fact that he's in love with Brady's daughter Jane (Jacqueline Wells, aka Julie Bishop). (allmovie.com)
