After chasing an unexplained capsule through time, the TARDIS lands in London, during an air raid.

After floating above the city on a barrage balloon, Rose is swept off her feet by another time traveller – Captain Jack Harkness. Meanwhile, The Doctor follows a teenaged girl to a meeting of the homeless children of the Blitz.
