With just nine days to the 50th Anniversary Doctor Who episode The Day of The Doctor, the BBC has released the mini-episode The Night of The Doctor, which features the return of Paul McGann as the 8th Doctor.
It appears the battle between the Time Lords and Daleks is
threatening to destroy the galaxy, but the Doctor appears not to be
involved. He answers a distress call only to discover the girl, Cass, he
intends to rescue, does not want Time Lord help and is willing to die
before she will. Her ship crashes on a planet, killing her and the
Doctor.
But the Doctor has arrived on Karn, home to the Sisterhood and The
Sacred Flame, which produces The Elixir of Life. The sisterhood is
remnants of the matricidal legacy that was the old ways of Gallifrey, long before the rise
of Rassilon and have dealt with the Time Lords for eons (the fourth
Doctor spent some time here during the TV adventure The Brain of Morbuis) ever since.
The Sisterhood resurrects the Doctor, only to give him a grim reality: he cannot avoid the battle and the galaxy will fall if he does not help. So death or regenerate (with help from the Sisterhood) and fight in the Time War. The Doctor
knows, of course, there is only one choice…
