Title: Something Wild
The uneventful life of the businessman Charles Driggs suddenly changes when he meets the wild and sexy Lulu. When he accepts her offer to drive him back to his office, she instead takes him out of town and on a trip, leaving behind his old life. Posing as a married couple, Charles and "Audrey" (which turns out to be Lulu's real name) visit her mother and her high school reunion. At this reunion they meet Audrey's violent ex-husband Ray, who has just released from prison. When Ray makes it clear that he wants Audrey back, that is when the real trouble begins.
