It's still Manhattan. There are still Daleks. They attempt to create a race of Daleks in human bodies, using the Empire State Building as a lightning rod. Dalek Sec is now part human, which the other Daleks really don't like. The new hybrid species and Dalek Sec are killed off by the rest of the Cult, and two of the remaining pure Daleks die in the process. Dalek Caan escapes to series 4. Laszlo is kept alive by the Doctor using the Daleks' genetics lab, although he'll be half pig forever. Talullah doesn't mind too much.
