It's off to Scotland after the Tomorrow People twice share the same nightmarish dream of a headless Highlander and a daydream about the kelpie (Lock Ness monster). Blame Andrew Forbes, a newly emerged Tomorrow Person doing what he can to save his father's failing hotel business (despite his devout father's stern displeasure as to how, thinking it Devil's work).—statmanjeff
Mike and Hsui Tai track down Andrew, but he is so scared by recent experiences that he uses his illusions to escape them. The Tomorrow People manage to convince Bruce and Angus of their good intentions and go in search of Andrew, but Andrew sends an army of illusions to stop them.—skteosk
John, Liz and Mike jaunt to Glip's ship, but when Yagon and Cantor return, they use the barlamin to disable them. The only hope of stopping their plans lies with Andrew and Hsui Tai, but the barlamin has already robbed them of their powers.
A shopping trip sees Mike and Hsui Tai purchasing the new bubbleskin jumpsuits. When they subsequently exhibit strange behaviour, the other Tomorrow People wonder if there is more to the new fashion craze than meets the eye.
With Mike and Hsui Tai partially removed from the Bolboid influence, bubblesuits take over John and Elizabeth to target Andrew. In stunning them, Elizabeth's suit won't come off but John's does, giving them the idea to combat the invasion with an epidemic.—statmanjeff
