A massacre survivor (A.J. Cook) studies serial killers under a famous expert (Bruce Payne), but her classmates soon start dying at the hands of a Jack the Ripper copycat.

An ex-con moves into an old apartment building, where he encounters a domestic problem involving a police officer, his wife, and their daughter. When he tries to intervene, however, a mysterious curse entraps him.

In February, 2001, Robert Hanssen, a senior agent with 25 years in the FBI, is arrested for spying. Jump back two months: Eric O'Neill, a computer specialist who wants to be made an agent is assigned to clerk for Hanssen and to write down everything Hanssen does. O'Neill's told it's an investigation of Hanssen's sexual habits. Within weeks, the crusty Hanssen, a devout Catholic, has warmed to O'Neill, who grows to respect Hanssen. O'Neill's wife resents Hanssen's intrusiveness; the personal and professional stakes get higher. How they catch Hanssen and why he spies become the film's story. Can O'Neill help catch red-handed "the worst spy in history" and hold onto his personal life?
