 Money-hungry Sally Warren and thrill-seeking Peggy Banning disguise themselves as men to commit a series of armed robberies. They escape in stolen cars, but two of the robberies result in murder when Peggy develops a predilection for using her gun. The two are able to pass easily through Highway Patrol roadblocks that have been ordered to look for two men. After the second murder, Dan Mathews finds a lost eyebrow pencil near one of the abandoned stolen cars and advises his officers that the "men" may actually be tall women. Sally and Peggy manage to get through one roadblock, but Dan and his officers quickly converge on their hideout. The two are forced into a high-risk attempt to flee on foot in the rough terrain.
