Tropic of Cancer

“Inferno under hot sun.”

Fred Wright (Gabriele Tinti) and his wife Grace (Anita Strindberg) take a holiday in Haiti, and the killings begin around them soon after they arrive. The murders are savage, and they lead back to a doctor (Anthony Steffen) and the new drug he has been testing, which produces extreme side effects in the people who take it. Lomi and Mulargia keep the couple close to the danger, with the vacation they came for now a place they may not leave.
