Inmates are systematically being murdered at Desert Counties, a maximum security State prison. Violence is not uncommon in the prison system, but assaults and deaths are generally resolved in short order and the perpetrators prosecuted. Not this time. There are no clues and no witnesses . . . at least none willing to talk. The Warden assigned the Investigative Services Unit (ISU) and the Mental Health Department to work together to unravel the intricacies surrounding each murder victim. To make matters worse, some ISU staff have been redirected to help State authorities in the escape of Frank Genter, a psychopatic killer who was being transported from Desert Counties to San Quentin State Prison to await execution. Aided by his brother Jake and Jake's White Supremacy motorcycle gang, Frank's escape allows him to settle some scores with those who betrayed him. Fred Makey (Mac), a veteran police officer and now Correctional Captain has been assigned to help the ISU on both matters. Mac has successfully worked with the ISU and local authorities in the past and is now faced with another two immediate crisis. Within the prison setting, an inmate on Mac's yard has been killed, adding to the growing list of unsolved inmate murders occurring on other yards. On the outside, the escapee, a very dangerous fugitive not only threatens the small prison community, but Mac's own family and friends as well.
