Peter Firth stars in the title role as a time traveller from Earth's future who illegally visits the London of 1980 to search for an 'ancestor' and finds a world very different from the one he left behind.

The story concludes with a plot twist involving a causal loop, a popular concept in time-travel fiction.

Despite the risks involved and the promise of trouble from his superior, Caleb Line, Dominick visits the flipside again.

Having narrowly avoided causing a fatal accident on a previous landing, Dominick realises the danger involved, and decides to visit the flipside once more, where he provides for Jane and his son by fetching them the following week's newspaper, from which Jane can use the soccer results to win the football pools.

[1] The play's theme, "You'd Better Believe It, Babe" was written by Rick Jones, and performed by his band, Meal Ticket.

Neither play was shown again on British television until 26 February 2006, when The Flipside of Dominick Hide was broadcast on BBC Four to tie in with a series of programmes about time.
