Live Fast, Die Young (1958)

Two sisters live in a dysfunctional family in a California town. The elder, "nice" Kim, was sexually abused and hates men. Rebellious teen Jill is fed-up generally and runs away, finding her niche as a B-girl and sex-kitten working her way to Vegas. Kim leaves her job and goes in search of Jill, meeting her own misadventures en route; but by this time Jill's wanted for robbery. Will she live fast and die young?
