Captain Jack Harkness:  It 's _ 1941 _ . The height of the London Blitz . The height of the German bombing campaign . But something else has fallen on London , a fully - equipped Chula warship . The last one in existence , armed to the teeth . And I know where it is . Because I parked it . If the Agency can name the right price , I can get it for you . But in two hours , a German bomb is gon na fall on it and destroy it forever . That 's your deadline . That 's the deal . Now , shall we discuss payment ?
