Suspect Zero is a 2004 thriller, directed by E. Elias Merhige. It opened to decidedly mixed reviews, and failed to earn back half of its estimated $27 million production costs at the box office. It has also been criticized to have a similar ending as the movie Se7en.
FBI Agent Thomas Mackelway (Aaron Eckhart) and Agent Fran Kulok (Carrie-Anne Moss) are put on the trail of Ben O'Ryan (Ben Kingsley), a serial killer who exclusively targets other serial killers. As the investigation proceeds, the agents begin to become aware of the possible existence of Suspect Zero, a mythical "super serial killer" responsible for hundreds of deaths across all 50 States who leaves no evidence behind to link his crimes together. The agents must decide if O'Ryan is the key that will allow them to catch Suspect Zero, or if he is Suspect Zero himself.
As it turns out, O'Ryan was part of a secret government experiment attempting to cultivate telepathic abilities in individuals for military purposes. The experiments gave O'Ryan the ability to see the actions of serial killers. These disturbing visions constantly torment O'Ryan, and drive him to find the killers and kill them. O'Ryan seeks out Mackelway because Mackelway shares his abilities to some degree and was involved in a controversial case that made headlines. O'Ryan hunts down Suspect Zero, whose child victims are giving O'Ryan even more nightmares.
