Maddog Malone has lived a life of high adventure and high stress working as a consultant for various big-city mobs. After a health scare, he decides to give up that life style and retire. He lands in Puerto Rico looking to make a new home and life for himself, and using his own aircraft, start a small airline charter business.

With a dubious past like his, however, settling down to a quiet existence proves futile. Standing in his way are a number of aggrieved former associates with scores to settle. Almost immediately after touching down, Maddog finds himself plunged into a world of corrupt bureaucrats, saboteurs, local gangs, foreign mobsters and blood feuds. Even his friends harbor secrets, and nobody, it seems, is about to let Maddog go quietly into the breezy, tropical sunset.
