Following the departure of a previous assistant, a gobby loudmouth woman on her way to an important event in her life gets warped into the TARDIS by an alien force. With no choice but to unwillingly stick together, the Doctor and Lucie wind up on a desperate colony planet that the Daleks are fucking up because there's an impure breed of their species being created out of disgusting h00munz by some Davros-lite scientist person (a.k.a, Hayley Atwell).
