It’s been 200 years since the Doctor left Messaline, and he is far from forgotten. Sadly the planet is once again preparing for warfare. The humans and H’ath have been getting along smoothly since the Doctor’s departure but a new race of Daleks are starting to take out planets one by one. First Jaffacad, then Bluir and now Riddana, Messaline is next on the list. After Messaline's civil war between Human and H'ath the people machines were taken, locked away by the government. They didn't need someone creating another army, with which another civil war could break out. The Daleks have their sights set on Messaline and they are destroying all transport (which contains lifeforms) that leaves Messaline. There is no way for anyone to leave and look for the Doctor. The only advantage is that the Dalek scans don't read 'children of the machine' as lifeforms. Desperate, they find a volunteer athlete and use a single cell to create another machine person. They name her Jenny, after the Doctor's daughter who was created the same way. In less than two weeks they train Jenny to complete the impossible task of finding the Doctor...

The Tenth Doctor has a new companion who's willing to risk everything to take him back to his old companion. There's something wrong with the human Doctor and the Doctor realizes that while losing one person, he also has a second chance at gaining back his one love, Rose Tyler.
