Only a month in to its freshman season and Alcatraz has already raised many mysteries. We've been dissecting them each week in hopes of figuring out the answers.
To recap: San Francisco detective Rebecca Madsen (Sarah Jones) and Alcatraz expert Diego Soto (Jorge Garcia) were enlisted by federal agent Emerson Hauser (Sam Neill) to track down a group of Alcatraz prisoners and guards who mysteriously vanished into thin air in 1963. Dubbed the '63s, the men are returning to present day with missions to track down keys that apparently unlock a secret "downstairs" door at the prison where... well, we don't know that yet, but we do know the prison doctors were taking the prisoners' blood, and Tommy Madsen (David Hoflin) was begrudgingly at the center of it.
