Sarah Jane Smith was meant to die, but on the day of her death, a man showed up on her doorstep who hadn't seen her in a very long time, the Doctor, now in one of his final bodies. He offers to take her with him for one last jaunt around the universe, for old time's sake.
This story is intended as a continuation of Sarah Jane Smith's life after her final story and is dedicated to Elisabeth Sladen and Tom Baker for enriching our lives for so many years.
