The clock is ticking when an inmate escapes Tennessee Prison. Squad Special Agents John Fisher and Richard Metcalfe lead a statewide manhunt to capture the fugitive before he reaches state lines. The stakes are raised when the Squad's investigation reveals that the fugitive is a spurned lover that may be out for revenge.

Prison crime doesn't rest for Special Agent John Fisher's birthday. With inmate drug use at an all-time high, the Squad searches for the source of drugs coming into the prison. John goes undercover to monitor prisoners' visitors, search an entire cellblock for evidence, and work with an inmate informant to set up a sting on the outside. But ultimately, the investigation leads John to the last place he wanted to look.

In the hands of a dangerous Aryan Nation leader, a cell phone becomes the means to give gang orders and run a violent criminal enterprise. Tired of finding cell phones, drugs and other illegal items inside the prison, Investigator Nicky Jordan decides to attack the source--smugglers on the outside. A surprise search of hundreds of prison visitors uncovers an illegal drug operation and deadly material packaged for smuggling.

An inmate with a shank sticking out of his stomach is rushed to the infirmary. No witnesses. No security video. Just before losing consciousness, the victim gives Special Agent Joe England a big lead on the case. But nothing about Joe's investigation seems to add up. Who stabbed the victim? Was it the Aryans, another gang or some kind of personal vendetta? Squad Deputy Director Jerry Lester uncovers the mystery's shocking twist.

The Squad fears that prison gang members are running an extortion game when an inmate's family starts receiving violent threats from a mysterious caller with ties to the Crips.

The warden receives an anonymous letter from an inmate threatening to raise a small army to attack correctional officers. Sgt.

Squad Deputy Director Jerry Lester and Special Agent Richard Metcalfe investigate a major drug smuggling operation potentially connected to the Crips and abetted by a source outside the prison. A case that involves cocaine, morphine and a bizarre love triangle lead the Squad into the community for a dramatic street bust.

After an altercation inside the cellblock, an inmate collapses and dies from multiple stab wounds.
