For centuries, a secret Order of priests has existed within the Church. A renegade priest, Father Alex Bernier, is sent to Rome to investigate the mysterious death of one of the Order's most revered members. Following a series of strangely similar killings, Bernier launches an investigation that forces him to confront unimaginable evil.
