Classic Doctor Who duos are reunited as they board a very special TARDIS on a nostalgic voyage through space and time.

Time itself is in peril! The Time Lords and UNIT find themselves besieged by a mythic figure from the Time Lords' past hell-bent on destruction. The only way to defeat him is to break the First Law of Time and let the Doctor help himself — literally...

The adventures of The Doctor, a time-traveling humanoid alien known as a Time Lord. He explores the universe in his TARDIS, a sentient time-traveling spaceship. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Along with a succession of companions, The Doctor faces a variety of foes while working to save civilizations, help ordinary people, and right many wrongs.

Hancock's Half Hour is a BBC radio comedy, and later television comedy, series of the 1950s and 60s written by Ray Galton and Alan Simpson. The series starred Tony Hancock, with Sid James; the radio version also co-starred, at various times, Moira Lister, Andrée Melly, Hattie Jacques, Bill Kerr and Kenneth Williams. The final television series, renamed simply Hancock, starred Hancock alone. Comedian Tony Hancock starred in the show, playing an exaggerated and much poorer version of his own character and lifestyle, Anthony Aloysius St John Hancock, a down-at-heel comedian living at the dilapidated 23 Railway Cuttings in East Cheam. The series was influential in the development of the situation comedy, with its move away from radio variety towards a focus on character development.
