VIDEO: DOCTOR WHO Unveils 'Time Heist' Teaser

BBC America will premiere a new episode of DOCTOR WHO -- "Time Heist" -- as part of its 8th season on Saturday, September 20 at 9/8c. Check out a teaser below!

This week, The Doctor (PETER CAPALDI) turns bank robber when he is given a task he cannot refuse: steal from the most dangerous bank in the cosmos. With the help of a beautiful shape-shifter and cyber-augmented gamer, the Doctor and Clara (JENNA COLEMAN) must fight their way past deadly security and come face to face with the fearsome Teller, a creature of terrifying power that can detect guilt... With special guest Keeley Hawes (Ashes to Ashes, MI-5).

ABOUT DOCTOR WHO: The truth about River Song is out and the time has come for the Doctor to face his greatest demons. Venturing across centuries and galaxies, the Doctor, Amy and Rory will encounter the greatest war criminal in all of history-and Hitler. Together, they'll discover there's no scarier place in the universe than a child's bedroom and a visit to an alien quarantine facility will reveal to Rory a very different side to his wife. In a hotel where walls move, corridors twist and rooms vanish, death lies waiting. But the Doctor's time has yet to come. He has one last stop to make on his final journey-an old friend needs his help and an old foe must be defeated. But time catches up with us all and the Doctor can delay no more.

Doctor Who is the continuing saga of a mysterious time traveler who picks up human companions and faces evil foes with little more than his wits and a sonic screwdriver while he journeys throughout time and space in the TARDIS-a unique craft disguised as a police call box. As the famed Whovian Craig Ferguson once said, it's about "the triumph of intellect and romance over brute force and cynicism."
