Nyssa will die at dawn, and the Doctor doesn't even know why.
To save her life, he must make a desperate journey to the only place in the universe where a cure might exist.
When even that fails, the Doctor has a choice let Nyssa die, or make a deal with the devil. After all, the road to hell is paved with good intentions.
