Tony Rome is an ex-cop turned private eye in Miami Beach. For $200 he returns a young woman to her father's house after she passes out in a seedy hotel, and he keeps the hotel's name out of it. Trouble is, she's missing a diamond pin, and tough guys show up at Tony's boat looking for it. When the pin does turn up, it's fake, so the girl's father, a wealthy builder, hires Tony to find out what happened to the real stones. Bodies pile up, Tony suspects the builder's trophy wife, and he's also looking for a mysterious guy named Nimmo who used to date Ann Archer, a stunning redhead Tony meets at the builder's. Can Tony sort it out before too many die, and what about Ann?
