Doctor Who (1963)

The TARDIS is attacked by the Rani, causing a crash‐landing on Lakertya. As the Sixth Doctor regenerates into his Seventh incarnation, he falls victim to post-regenerative confusion and is tricked by the Rani—disguised as Mel—into helping repair mysterious machinery. Meanwhile, Mel is separated and makes first contact with Lakertya natives, including the rebellious Ikona, while trying to flee from the Rani’s minions.
