While a serial killer continues to taunt and terrorize San Francisco residents, police detective Jon Lucca (Edward James Olmos) doggedly follows his tracks. Unlike other members of the department, Lucca does not believe the main suspect -- who was shot over a decade ago in a police gun battle -- was the guilty person. Still, Lucca firmly believes in the justice system and refuses to launch his own investigation, preferring instead to wait cat-like for the killer to make a mistake. The trouble is, the concentration required becomes obsession. As time passes, the obsession slowly erodes his sanity. Originally aired on cable, this taut psychological thriller ranks as one of the better entries in the genre.
