A crime lord named Caleb Hooks, who Walker helped put in prison several years ago, escapes from prison, bent on revenge against the Rangers because his brother had been shot and killed during a shootout, and he claims it was murder. He initiates his plan by having Alex and Trivette kidnapped, then placed in a huge tank full of freezing, running water. He then contacts Walker and begins playing cryptic games with him, in hopes of both luring him into a death trap of his own and stalling him in his efforts to rescue Alex and Trivette before they drown.
