When San Francisco Police Department Det. Rebecca Madsen (Sarah Jones) is assigned to a grisly homicide case, a fingerprint leads her to Jack Sylvane (Jeffrey Pierce), a former Alcatraz Island prisoner who died decades ago. Given her family history both her grandfather and surrogate uncle, Ray Archer (Robert Forster), were guards at the prison Madsen's interest is immediately piqued, and once an enigmatic, government agent Emerson Hauser (Sam Neill) tries to impede her investigation, she is doggedly committed.
Madsen turns to Alcatraz expert and comic book enthusiast Dr. Diego "Doc" Soto (Jorge Garcia) to piece together the inexplicable sequence of events. The twosome discovers that Sylvane is not only alive, but he is loose on the streets of San Francisco, leaving bodies in his wake. And strangely, he has not aged a day since he was in Alcatraz, when the prison was ruled by the iron-fisted Warden Edwin James (Jonny Coyne) and the merciless Associate Warden E.B. Tiller (Jason Butler Harner).
Poor Hurley, already typecast as the fat comic nerd.
