chunk: A man is seated in a diner who is revealed as Harold Speck, a traveling salesman. He is joined by a gentleman who asks question which make him uncomfortable. After leaving the diner, Harold is found dead, with his eyelids cut off and clutching a symbol which appears to be a circle with a line through it, which leads to FBI Agents Thomas Mackelway (Aaron Eckhart) and Fran Kulok (Carrie-Anne Moss) being brought in on the case. There appears to be history between Mackelway and Kulok. We learn Kulok has been married but it didn't work out. Before that she was with Mackelway. Flashbacks of Mackelway's recent suspension reveal he received a six-month suspension and psychological evaluation for beating a suspected serial killer, Raymond Starkey (who was in fact a serial killer and went to prison for his crimes). Mackelway receives a series of taunting faxes from someone who may be the killer. Meanwhile, kids go missing and we catch glimpses of a big truck.
