Ms. Moxie Mooney is Hollywood royalty—and she's in trouble.

At the summons of his on-again, off-again lover, Fletch drops in on Moxie's film set, located in sunny Florida. If being called up for help by the box office beauty isn't work enough, Steve Peterman, Moxie's sleazy manager, is murdered while the cameras are rolling, and no one managed to see a thing. Despite the obvious lack of evidence, the rumor mill is still quick to churn up a potentially plausible suspect: Moxie.

Realizing the need for a little R&R away from prying eyes, he hastily flies Moxie and her drunken father off to Key West. But trouble follows Fletch, in every sense of the word, and soon enough he's playing host to a full house of Hollywood's brightest.

In true Fletch style, he delves into the investigation, dodging police inquiry, betting on race horses, taking a leisurely sail, and talking up his elite houseguests to get the dirt and solve this perplexing murder.
