Having been conned into keeping the Blue Moon Detective Agency alive, Maddie Hayes (Cybill Shepherd) reluctantly agrees to team up with arrogant private eye David Addison (Bruce Willis) to solve their first "official" case. A man (Pat Corley) has come to the agency in hopes of locating his long-lost son Michael (Gary Graham). Following the trail of clues, the detectives discover that Michael is a professional contract killer--but they haven't the heart to tell Michael's father. What they don't realize is that dear old dad is likewise a professional hit man, and that father and son have been assigned to knock each other off!
