==== ''The Day of the Clone'' ====
The final serial ties together many of the elements of the previous serials. Believing that Beth needs her help, Liz attempts to return to 1990 via the Time Barrier, but is kidnapped by Traynor. Simon goes looking for Liz and tracks her to R1, a secret research establishment under Traynor's command, that is located at St. Oswald's and next to the Time Barrier. The children learn that R1 was established by Morgan C. Devereaux to research into the longevity drug – HA57 – that the children previously encountered in the Ice Box. They break out of R1 and, with Traynor in pursuit, they make their escape through the Time Barrier, which transports them to the year 1965. Realising that Devereaux would have been alive in this time, they return to R1. There the children learn that R1 is not only researching longevity, but also cloning. Devereaux believes that for the cloning and longevity process to be a success, subjects must also undergo psychological reconditioning, but Traynor, who is working at R1 as the Government's representative, disagrees, believing that Devereaux is turning the volunteer subjects into brainwashed puppets. When Traynor threatens to shut down R1, Devereaux has him detained and replaced by a clone. Devereaux's experiments fail and the young people Simon and Liz encounter at R1 in 1965, they meet again in 1970 only now they are all very old men and women on the point of dying. Simon realises that it is Devereaux who is the source of the dystopian futures they have witnessed, and that the Traynor they know has been a clone all along. The Time Barrier created a clone projection of Devereaux in the Ice Box in the hope that the children could return a working formula for HA57 to the Traynor clone in 1970. The Traynor clone is also a projection of the Time Barrier, charged with implementing Devereaux's vision of the future: the catastrophic Master Plan that will lead to the "Burn Up". Returning to 1970, Liz and Simon discover the real Traynor, locked up in a secret room in R1 since 1965. The children and the real Traynor confront the clone Traynor at the Time Barrier at St Oswald. Traynor tells the clone that he does not exist, that he is a projection. As the clone nears the Barrier, an invisible force grabs him and he disappears into the Time Barrier. Liz and Simon return to their families, leaving the real Traynor alone.
