When an old fisherman is gunned down on a Mexican beach, prominent Miami surgeon Raymond Peters becomes the prime suspect. The dead fisherman is believed to be Fidel Castro, whom Peters helped disguise through clandestine plastic surgery on a trip to Cuba two years earlier. In order to save his own life, the beleaguered doctor must find the killers and retrieve a mysterious journal while outwitting a ruthless woman assassin named Marcela, sent by Castro's brother Raul.
