Classic Doctor Who

The TARDIS suddenly arrives on the Earth colony of Vulcan. While they are there the newly-regenerated Doctor decides that he must assume the brand new identity of an Earth Examiner.

Posing as an Examiner from Earth, the Doctor warns the scientist, Lesterson about the dire consequences of reactivating the dormant Daleks.

Polly is taken prisoner by the rebels who intend to use the Daleks to take control of the colony; the Doctor discovers that all three Daleks have been reactivated.

Lesterson is driven insane when he discovers that the Daleks are reproducing themselves, and are preparing to seize control of the colony.

Bragen leads the rebellion and takes control of the colony, killing Governor Hensell, but the Daleks are also ready to make their final move.

With Bragen in charge, the Daleks trick the rebels into freeing them; only the Doctor stands in the way of the Daleks wiping out the colony.
