From executive producer J.J. Abrams (Fringe, Lost, Star Trek) comes Alcatraz, a chilling new drama revolving around America's most infamous prison and onetime home to the nation's worst criminals.

When San Francisco detective Rebecca Madsen is assigned a grisly homicide case, a fingerprint leads her to Jack Sylvane, an Alcatraz inmate who died over 30 years ago. With a family history involving the prison, Madsen's interest is immediately piqued. And once the secretive government agent Emerson Hauser tries to impede her investigation, she's doggedly committed.

Turning to Alcatraz expert Dr. Diego "Doc" Soto to piece together the inexplicable sequence of events, the two discover that Sylvane is not only alive, but loose on the streets of San Francisco, exacting decades-old revenge and leaving bodies in his wake. And, strangely, he hasn't aged a day since 1963.

Reluctantly teaming with Hauser and his technician, Lucy Banerjee, to stop Sylvane's vengeful killing spree, Madsen and Soto delve into Alcatraz history, government cover-ups and Madsen's own heritage, to discover that Sylvane is only a small part of a much larger, more sinister present-day threat. For while he may be the first to reappear from Alcatraz, it quickly becomes clear that Sylvane won't be the last.
