S02E01: 'New Earth'

It's the year 5 billion and 23 in the galaxy M87. The Doctor and Rose land on New Earth, the new home for the human race following the destruction of the original Earth by the expanding sun.

The Doc receives a psychic paper note beckoning him into a health centre run by suspicious-looking cat nuns. There he meets the Face of Boe, who is dying of old age.

Meanwhile, elsewhere in the centre, Rose stumbles across an old foe - Cassandra - who wants a new body...

As the visitation continues, things take a turn for the worse when a huge human farm harbouring all plagues of the universe is discovered. What are the cat people really up to? And will Cassandra get her wish for eternal life?
