BBC America has released the third trailer for Season 7 of Doctor Who, debuting Saturday, September 1 at 9 PM ET with Asylum of the Daleks, the first of five new episodes in a row. This season will also wrap up the story line of Karen Gillan's Amy Pond, before the Doctor's new companion (Jenna-Louise Coleman) debuts in the Christmas Special this December. Take a look at the latest video from this highly-anticipated season.

Kidnapped by his oldest foe, the Doctor is forced on an impossible mission - to a place even the Daleks are too terrified to enter.... the Asylum. A planetary prison confining the most terrifying and insane of their kind, the Doctor and the Ponds must find an escape route. But with Amy and Rory's relationship in meltdown, and an army of mad Daleks closing in, it is up to the Doctor to save their lives, as well as the Pond's marriage.
