In the 1986 movie Something Wild Charles (played by Jeff Daniels) a relatively boring office worker is seduced/kidnapped by "Lulu" (who is actually Audrey, played by Melanie Griffiths) for some wild scheme she has cooked up which initially involves a seduction, a motel room and handcuffs). She later takes him to visit her mother and her High School reunion while pretending he is her husband. Then things go dark when her actual husband turns up having been released from jail unexpectedly.
Before the dark, violent turn when her ex-husband turns up (which she didn't expect) what was Audrey's plan and how did she expect her shenanigans to end?
