In a maximum-security prison, Walker poses as a hit-man to get evidence on an incarcerated racketeer who's had a key witness and two Rangers killed.

The criminal that killed Walker's fiancé ten years ago is being released early from prison. He intends to seek revenge on Walker for putting him away by hurting all of Walker's friends.

Trivette's brother Simon is in town with drug dealers, trying to arrange a big operation. The Rangers are determined to stop the organization. Simon is told he has to kill his brother.

Walker, Trivette, Alex, Gage and Cooke go to another city to play baseball with the city's police department. Alex meets with the D.A. who is a friend to talk about a major drug bust they made. Later two cops are waiting for someone when three detectives come in and try to kill them. One of them is killed, the other gets away. He makes his way to the courthouse and the detectives chase him, he runs into the D.A.'s office and they shoot the D.A. Walker shows up and tells them to get out. He then talks to the cop who claims that he has proof that the three detectives are stealing drugs from their busts. Walker finds it hard to believe and sends Gage and Cooke to look into it and learn it might be true. Walker thinks that one of the city's high ranking cops might be working with the detectives.
