This week on Doctor Who:
A surviving Slitheen, masquerading as the mayor of Cardiff, plans to construct a nuclear reactor in order to tap into the power of the time rift running through the heart of the city. The Doctor, Rose and Jack set out to stop her and turn her over to the law on Raxacoricofallapatorius. But the Doctor is faced with a difficult choice when it is revealed that the Slitheen faces a death sentence on her homeworld.
And next week on Doctor Who: a whole shitload of Daleks!
