Steve Ford (Bruce Willis) is a down but not out L.A based Private Investigator whose professional and personal worlds collide after his loving pet Buddy is stolen by a notorious gang. A series of crazy circumstances find him doing the gang's bidding, while being chased by two vengeful Samoan brothers, a loan shark's goons, and a few other shady characters. They say a dog is a man's best friend, and Steve shows how far a man will go to be reunited with him.

After a clumsy operation trying to capture a drug dealer, the N.Y.P.D Detectives Jimmy Monroe and Paul Hodges are suspended for one month by their Captain Romans. Jimmy decides to sell his rare baseball card to pay for his daughter's expensive wedding while his jealous partner believes that his wife is cheating on him with their next-door neighbor. When Jimmy sells his card to a memorabilia store, the place is burgled by two small-time thieves and the detective loses his card. They track down the thieves.
