Imagine accidentally ingesting a strange powder and being haunted by nightmarish visions -- memories of a shadowy predator who abducts young girls. That's what happens to Dr. Taylor Briggs (Billy Zane) when he is exposed to a mysterious drug while lecturing in Brazil. Forced to relive the dark, twisted memories of a killer, Dr. Briggs embarks upon a lone journey to unlock the mystery of a past that is not his own -- and find a killer whose horrifying work may not be over.
