When ambitious Doctor Paul Clement takes a job at the mission hospital on Saint Sebastien he has dreams of discovering cures for tropical diseases. What he finds is a place where the black arts are just a way of life. After witnessing the ritualistic murder of a young man said to be one of the living dead he is forbidden to speak of what he has seen. On returning to Paris Clement's attention turns to studying the nervous system & resuscitation. He is told of patients who have apparently died been brought back to life & whilst suspended between life & death experience what they believe to be heaven. Clement attempts a daring experiment in order to confirm these extraordinary reports but the outcome is wholly unexpected. Could it be that when he is resuscitated he brings something back with him
- an ancient evil so powerful that it can never be destroyed? Is the good doctor slowly succumbing to madness or has he really passed through the gates of hell?
