When San Francisco Detective Rebecca Madsen (Sarah Jones) is assigned to a grisly homicide case, a fingerprint leads her to a shocking suspect: an Alcatraz inmate who died over 30 years ago. Once the enigmatic, knows-everything-but-tells-nothing government agent Emerson Hauser (Sam Neill) tries to impede her investigation, Madsen turns to Alcatraz expert Dr. Diego “Doc” Soto (Jorge Garcia), to help her piece together the inexplicable sequence of events. By delving into Alcatraz history, government cover-ups and Rebecca’s own heritage, the team will ultimately discover that this reappearance is only a small part of a much larger, more sinister present-day threat. For while he may be the first, it quickly becomes clear that this fugitive won’t be the last to reappear from Alcatraz.
