Years ago when the most dangerous prisoners of Alcatraz mysteriously disappeared, they resurface in the present day as part of a larger conspiracy, leaving a police detective, an expert on Alcatraz and an FBI agent to track them down.

Guy Hastings, an Alcatraz guard, reappears. Although a good man, Hastings is being asked to do bad things and will come face-to-face with an old acquaintance.

Rebecca, Doc, and Hauser set out to capture musically-inclined serial killer Webb Porter, an unknown ’63 that returns more violent than ever.
