Gene Hackman is Harry Moseby, a cut-rate private detective who just isn't very good at what he does. Most of his cases are routine and very dull. When a wealthy woman hires him to track down her missing daughter, Harry believes it to be just another missing-persons case. He locates the girl and brings her back home, despite the girl's protests. Days later she turns up dead and Harry suspects foul play. Soon Harry finds himself embroiled in a mystery that leads to smuggling rings, double-crosses, and seductions. The inexperienced gumshoe finds himself totally out of his league as he is caught in the middle of this dangerous web of lies and murder. Hackman is excellent as the somewhat soft-boiled detective who's job is making him increasingly paranoid. Melanie Griffith is also a standout in her movie debut as Delly, the promiscuous Lolita whom Harry is sent to find.
