Meet Sarah Jones, an actress most recently seen on "Sons of Anarchy," who has been cast as the lead in J.J. Abrams' new show "Alcatraz." She will play a police detective investigating the Alcatraz case (mentioned below). She joins Jennifer Garner and Anna Torv (Fringe) as J.J.'s hand picked leads.
We also now know some details of the show's plot. It involves several Alcatraz prisoners and guards who went missing at the prison 30 years ago and reappear in the present day. Jorge Garcia (Lost's Hurley) plays a modern day Alcatraz expert.
