Detectives Randy Loboda and Phil Harding find two bodies, burned up, in the opposite side of town on the same night. Loboda's investigation leads to a motel where they find a bloody room, the possible murder scene, while Harding learns the two victims may have been killed by the same killer; Sergeant Joe Schillaci finds a man's body, a victim of an apparent suicide, but his investigation takes a twist when he discovers signs of a struggle. Schillaci soon learns the man was seen with a mysterious woman only hours before his death, but the woman has disappeared. She may be the killer or yet another victim.
