The uneventful life of business-man Charles Driggs (Jeff Daniels) suddenly changes when he meets the wild and sexy Lulu (Melanie Griffith). 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 highschool reunion. At this reunion they meet Audrey's violent ex-husband Ray, who's just released from jail. When Ray makes it clear that he wants Audrey back, that's when the real trouble begins.
