I had this idea quite a while ago, but haven't had a chance to use it.

In 2060s Earth, there is about to be an attempt to travel between universes. The TARDIS lands during the test, and it and all it's occupants are sent to a universe where the Flood successfully invaded Earth. They arrive in a roofless warehouse. Groups of people rush into the room and order them to get out, though they ultimately all have to be dragged away and are seperated. They are informed they were taken away so that they would not be infected by the water. All of the universe's natives are infected, some giving up and going willingly. The Flood eventually evolves to the degree the death of the host will not stop it. The Doctor and companions re-group over the course of the story and make it back to the TARDIS, by which point the technicians in the original universe have figured out how to return them.

If this was in the series, my choice of title would be 'The World on Fire'.
