Heaven or Vegas (1998)

Rachel, a part-time call girl, consumed with fairy tales, is taken off the streets of Las Vegas by Navy, a high-class gigolo in search of a new way of life in Montana. Along the way, the couple is sidetracked when they decide to stop at the home Rachel ran away from six years ago. Navy nearly falls for Rachel's gorgeous and "virginal" step-sister, Lilli. Heartbroken, Rachel runs away just as Navy realizes she is the one for him. He dramatically rescues her from psychotic drifters.
