Hole (1970)

Kevin and Mia are con artists, a kind of modern Bonnie & Clyde, who seduce and rob women, the rich, divorcees and widows. Kevin's enormous sexual appetite and Mia's morbid jealousy lead to the robbery of the rich seductress Emma. Believing that they have killed her, they drive deep into a remote forest where they plan to bury her body. While they are digging a cave, Ema wakes up and runs away, Kevin and Mia go after her. A game of cat and mouse begins, a struggle for life and death, but nothing is as it seems at first glance.
