Fifty years ago, Alcatraz prison was closed, all inmates officially shifted to a more modern facility. In fact jailer Emerson Hauser was among those who witnessed dozens of hardened criminals disappearing mysteriously at once. He joined the FBI and heads a secret division to hunt them down now. The first target is Jack Sylvane, dubiously convicted and mistreated, who now exacts bloody revenge on long-retired deputy warden E.B. Tiller. The affair allows recruiting Alcatraz-obsessed genius Dr. Diego Soto and San Fancisco PD detective Rebecca Madsen, who seems somehow destined. Written by KGF Vissers

The next returning Alcatraz inmate is Ernest Cobb, a crack-shot who shot series of crows and people in different cities all over he US before being arrested. He deliberately shot a guard in the leg to be relocated to Alcatraz, hell-bent on a quiet, private cell. Warden Edwin James sadistically kept denying him isolation, leading to more inside crimes. Diego 'Doc' Soto's knowledge proves invaluable to catch Cobb before he makes his third victims batches before moving to another time, but the stress and danger of the chase make him doubt if he's fit as SFPD partner. Emerson Hauser remains frustratingly secretive and again seizes the recaptured villain for openly hostile 'interrogation', like Jack Sylvane's despite his claim to remember nothing.

The third monster returning from Alcatraz is the most despised yet: threefold convicted child murderer Kit Nelson kidnapped young Dylan Callahan from his bed, terrifying kid brother Liam to silence. Diego 'Doc' Soto realizes his MO is to spend the weekend with him and return the corpse home and breaks emotionally when Emerson Hauser heartlessly sets up a trap there, but finds them himself, although that doesn't go well either. In 1960, Warden Edwin James heaped his cruelty on top of customary abuse by fellow inmates and prison doctor Milton Beauregard. Written by KGF Vissers

Cal Sweeney, the next Alcatraz prisoner to mysteriously reappear, resumes his MO of robbing banks, where he seduced a female teller clerk, limiting himself to the private boxes, not the safe, and returning with his loot to one client. Alas he is now more violent, once being surprised, next at a home. He's caught by helping him escape before a SWAT attack after his last robbery is detected. In 1960, Cal ran the prison's semi-condoned black market, training junior cell neighbor Harlan Simmons to become his deputy. After deputy warden E.B. Tiller confiscated the empty metal box Sweeney treasures above all, Harlan assists his plan to make a deal during the fancy birthday party the warden hosts for Tiller's anniversary, but that ends in bloody disappointment. Hauser and his back-room team care only for the key Sweeney stole. Written by KGF Vissers

The next man 'returning' from 1963 and hurting an Alcatraz island ranger is no prisoner but most senior guard Guy Hastings, who was in charge of training recruits. One of those, Ray Archer, seemingly was the pointless butt of convict Tommy Madsen, but actually a loyal relative. Dr. Diego Soto helps Rebecca work out her father-substitutive uncle's more significant position. Meanwhile Guy takes him hostage to look for his elusive heritage, is surprised to see his now adult daughter Annie has kids and grandkids and allows Hauser to bring him into the secret section.
