Dr Who: Time and the Rani

After an attack by the evil Rani, the TARDIS crash-lands on the desolate planet of Lakertya. On the floor on the console room, the Doctor begins his seventh regeneration... In his post regenerative confusion, the Doctor is seperated from his young companion Mel and tricked into assisting the Rani in her megalomanic scheme to construct a giant manipulator. Lost on the the barren surface of the planet, Mel has to avoid the Rani's ingenious traps and her monstrous, bat-like servants, the Tetraps. She joins forces with a rebel faction among the Lakertyans, desperate to end the Rani's control of their planet. The Doctor must recover his wits in time to avoid becoming a permanent part of the Rani's insane plan to drain the genius of the greatest scientific minds in the universe...
