Synopsis:
Chevy Chase is at his hilarious best in this suspense-packed comedy thriller based on Gregory McDonald's best-seller. Irwin M. Fletcher, aka Fletch (Chase), is an investigative reporter for a Los Angeles newspaper. In order to get scoops for his controversial stories, he changes his identity more often than his underwear, much to the chagrin of his frustrated editor (Richard Libertini).

While working on an exposé about drug trafficking, Fletch attracts the attention of a strange businessman, Alan Stanwyk (Tim Matheson) who hires him as a hit-man for himself. Stanwyk claims that he is terminally ill and wants his family to get the benefits of his insurance policy. Fletch agrees to murder, but he senses a scam and tries to uncover the truth.

Fletch ties the story together by checking out a ritzy tennis club, a Utah realtor's office and a pig farm. Soon he's up to his bylne in frame-ups, murder, police corruption and forbidden romance. It'll be the story of the year, if he can stay alive to meet his deadline!
