Walter Davis (Bruce Willis) needs a date for a dinner his company is having with a Japanese client. His brother Ted (Phil Hartman) sets him up with his
wife's cousin Nadia Gates (Kim Basinger). She's a sweet girl but she can't be given alcohol, because it tends to mess her up. Walter wants to get lucky, so they share a glass of wine early in the evening, and instead of getting lucky, because of her, he loses his job, his car gets messed up and he seemingly goes out of his mind.
Oh, and did I mention that Nadia's ex-boyfriend David Bedford (John Laroquette) still holds a torch for her, and may want to use it on Walter?
