Plot Summary

Father Xavier Meldrum is a Catholic priest with problems – obsessed with the promiscuous sex lives of the young women whose he hears, he tapes their intimate secrets and blackmails them. When his latest victim commits suicide, he sets his sights on Jenny Welsh. No-one who hears Jenny's claims believes a word of it and even her sister Vanessa believes that she is going mad. But bodies are starting to pile up and Vanessa overhears an incriminating conversation that seems to suggest that Jenny may have been right all along…
