Joyride to Nowhere(1977)

Overview:

Teenage friends Cindy and Leah have decided to leave their abusive homelives behind, stealing Cindy's father's car and setting out on the road to freedom. On the way, they meet up with a sleazy guy named Tank who invites them up to his place. As Tank showers, the two girls decide to take off, stealing Tank's wallet and his car. His car, however, happens to contain $2 million from a bank job he just pulled off, and Tank is now rather intent on tracking the pair down and reclaiming what's his.
