Six regenerations later the Doctor returns; and Ace, his travelling companion, sees London as it was before the Sixties started swinging - and long before she was born.

But a Grey Dalek is lurking in Foreman's Yard; Imperial Daleks are appearing in the basement of Coal Hill School; and both factions want the Hand of Omega, the Remote Stellar Manipulator that the Doctor left behind. Has the Doctor arrived in time to deprive the Daleks of the secret of time travel?
 

"Doctor, my men have just put three highly explosive grenades into a confined area. Nothing remotely human could have survived that."

But as the Doctor informs Group Captain Gilmore, the hostile agressor which has already killed one of his men is not remotely human. For London in 1963 is to be the allotted place and time for a further encounter between the Doctor and his most feared enemy - the Daleks.

Accompanied by a streetwise teenager from the 1980's called Ace, the Doctor must prevent the Daleks from capturing the Hand of Omega - the key to the control of time. But for this crucial encounter the Daleks pose a doubly sinister threat, for the Hand of Omega is sought by two opposed Dalek factions - the Renegade Daleks and the Imperial Daleks. Why have the Daleks splintered into these two factions and what, or who, is controlling them? These are the questions the Doctor must solve if he is to retain control of time itself...

Originally transmitted 5 - 26 October 1988, this four part adventure is released for the first time on BBC Video, in this antique souvenir tin, marking the 30th anniversary of Doctor Who.
