The other is a disturbed Zodiac killer, obsessed with the chase and determined to keep authorities one step behind. With the help of the coroner (Isaac Hayes), King sets out to track down the violent killers and put an end to the ongoing murders in the streets of Memphis. Explosive action sequences coupled with surprising twists and turns make KILL SWITCH a knock out.
