Roy Lee Brown

When two young lovers are savagely beaten and tortured on a back country road in Texarkana, local police are baffled and must find "the Phantom Killer" before he can kill again.

The unit specializes in the investigation of serial murders and is led by Van der Bijl, a former murder and robbery detective who gained fame for his handling of several high-profile cases. Each episode focuses on a serial killer. The main character, Colonel Piet van der Bijl, also known as Die Byl, is loosely modeled on the famous ex-detective Piet Byleveld.
