Time & The Earth (TV Story)

The Doctor and Hettie return to Earth in search of their runaway, and upon seeking help from old friends, Hettie and The Doctor are taken aback by Earth’s fractured state. For the newly re-established UNIT is no longer the same, and with Kate gone, and all familiar soldiers replaced, the Doctor’s only aid is the unfamiliar lady who stands at the head of UNIT, whose memory of Earth is non-sensical. Somebody has re-written Earth’s history, and they’ve signed their work: The Doctor.
