Mystery, starring Frank Sinatra, Jill St John, Richard Conte, Sue Lyon and Gena Rowlands.

Tony Rome, a tough Miami PI living on a houseboat, is hired by a local millionaire to find jewelry stolen from his daughter, and in the process has several encounters with local hoods as well as the Miami Beach PD.
