ALPHAS (SEASON 2 PREMIERE)
Premieres Monday, July 23 at 10PM
In Syfy's action-packed hit drama series, an unlikely team of ordinary people with superhuman physical and mental abilities - known as Alphas - takes on mysterious cases the CIA, FBI and Pentagon are unable to solve and go head-to-head with criminal Alphas.
Season 2 picks up eight months after last year's finale with the stage set for an explosive turn of events at the Binghamton facility (the Guantanamo of the Alpha world) that could have devastating, far-reaching consequences. Dr. Lee Rosen (Emmy Award-winner and Academy Award-nominee David Strathairn), having exposed the existence of Alphas to the unsuspecting public, finds himself discredited and imprisoned by a government desperate to cover up his revelation. The rest of the core team has disbanded and some, without Rosen's guidance and care, have regressed to their old, destructive ways. They must now battle their individual demons in order to reunite and try to save their own.
Alphas also stars Malik Yoba, Warren Christie, Azita Ghanizada, Ryan Cartwright and Laura Mennell. Erin Way (Detroit 187, Private Practice) joins the cast this season as "Kat" a mysterious young loner whose Alpha ability allows her to pick up any skill at a glance. But while her skills are permanent, her personal memories are short-lived. The series is produced by Universal Cable Productions and BermanBraun Television with executive producers Bruce Miller, Gail Berman, Lloyd Braun, Gene Stein and Zak Penn. Penn and co-executive producer Michael Karnow are series creators.
