Now that the new Doctor has gone on his first adventure, it’s time to get serious. On the next episode of “Doctor Who,” the Doctor and Clara are coming up against the Time Lord’s most legendary foes, the Daleks.
In two teasers for “Into the Dalek,” the Doctor and Clara end up on a rebel ship that also happens to be surrounded by the pesky alien menace. The second clip finds a member of the crew mistaking the Doctor for, well a doctor. A bit of Dalek surgery may be in order.

“Into the Dalek” sirs Saturday, Aug. 30, at 9 p.m. ET/PT on BBC America.
