The Doctor, Amy Pond and Rory Williams busy themselves rescuing survivors of an alien spacecraft that has crashed into a beach on 23rd century Earth. Feeling sorry for the poor little things, the Doctor leaves them in the hands of the emergency services and offers to pop by their homeland and let their nearest and dearest know that the survivors are OK. Reluctantly the aliens give their home world as Pirius Voon in the Grizellda Quadrant and the TARDIS leaves with its crew.
