Plot:
-----
While vacationing in Haiti with his wife Grace (Anita Strindberg), Fred Wright (Gabriel Tinti) decides to make an impromptu visit on an old friend, Williams (Anthony Steffen), a doctor.Fred's motives are not entirely pure, however, with it soon emerging that he is one of various parties interested in a new wonder drug that Williams has developed, some of whom will stop at nothing - including murder - to secure it for themselves. (Genre fans may be reminded of the plot of Bava's Five Dolls for an August Moon in this regard, with the brightly coloured visuals and Piero Umiliani's not dissimilar lounge score reinforcing this intertextual connection.)The first complication is that the idealistic Williams appears to have no interest in selling the drug, regardless of the price...The second complication is that the drug, the sample of which has gone missing, may in any case also have potentially fatal side effects for those who take it, with one of Williams's native assistants turning up dead soon afterwards, his blood being almost like water in its appearance and chemical composition...Although showcasing a number of characteristic giallo themes, being bookended by the arrival and departure of a Pan Am jet and featuring the obligatory unidentified black gloved killer (or killers) working their way through a swathe of victims, the gloves admittedly somewhat incongruous in the tropical setting, Death in Haiti AKA Tropic of Cancer offsets such routine elements thanks to its atypical setting (rum rather than J&B being the drink of choice) and the inclusion of some documentary style footage of cockfighting, a slaughterhouse and voodoo rituals.
