In 2008, both the Ninth and Tenth Doctors and their companions, Lynda Moss and Rose Tyler as well as Martha Jones and Donna Noble, travel back in time to the year 1998 in their respective TARDISes. In that year, Minerva McGonagall, the now-Headmistress of Hogwarts School of Witchcraft and Wizardry, invited the class of 1998 back to repeat their seventh year of education. Hogwarts is starting to rebuild itself, and only select ones that died, have been brought back to life. The worlds have collided, and there is now a new evil afoot and not even magic is going to help them. The TARDISes are now stuck in the village surrounding Hogwarts, Hogsmeade. The two Doctors and their companions must now learn that being magical isn’t just a fairy tale.
