Classic 8 part adventure on two ICT VHS tapes.
"After Liz and Simon return to the present, Simon is summoned to Whitehall by Traynor. Although the commander is still interested in the longevity drug that Simon saw in The Ice Box, he warns the boy to stay out of the future; however, this only serves to pique Simon’s interest. Liz realises that she misses Simon, and decides to join him; together they once more travel through the time barrier, this time arriving in an alternate version of 1990, in an England that is a lush, tropical jungle. Here the two children once more encounter Beth, but this alternate version is a much friendlier person because she did not take the intelligence enhancement treatment, and she is the leader of a commune of ‘misfits’ who live a primitive but simple life in the jungle. This version of 1990 is ruled by the Technocrats, a scientifically-advanced elite that has no interest in anyone of a lesser intelligence, and who are carrying out a Masterplan that will re-shape the world into a more ordered state. Unfortunately, these experiments are causing vast global-warming, and the Earth is rapidly drying up. Simon soon encounters a Technocrat known only as ‘2957’ – in truth Simon’s future self; together, the two of them travel to the future version of Whitehall, where they learn that sabotage is disrupting the Masterplan. With time running out Simon tries desperately to discover the identity of the saboteur, and he soon finds that it is none other than another future version of Commander Traynor. This alternate Traynor was the originator of the Technocrat Masterplan - and his scheme is about to cause the destruction of the entire planet in a blanket of fire…
