The Watcher 2001

FBI agent Joel Campbell has gone into hiding. Traumatized and beaten down after years of pursuing psychotic killers in Los Angeles, he is trying to carve a new, less stressful, life for himself in Chicago. But his guilty past follows him. He has only been in Chicago for a few months when there is a rash of gruesome murders, all of which follow a sickeningly familiar pattern: They are undoubtedly the work of one man - David Allen Griffin. The cunning and tormenting Griffin prodded and eluded Campbell for years in Los Angeles. And now he has pursued his tracker to Chicago. For Griffin, the vicious, merciless killing of lonely young women has merely become a pretext for a sadistic game of cat and mouse game between himself and Campbell. Before each murder he sends the FBI agent a photograph of his intended victim and dares him to find her before he strikes again.
