How would BIG try to brainwash him? And more importantly, how dare Caz call him a loser? He was furious, but he took some deep breaths. Stay calm, he told himself, she’s about to spill the beans on her evil plan. ‘Using Cinemania Studios as our front, we’ve shot a new spy movie, Covert Operations,’ said Caz, sounding thrilled with herself. ‘It’s packed with subliminal messages.’ Subliminal messages? thought Zac. He knew they were words or pictures in a film that flashed up too fast for you to notice. Subliminal messages could convince you to do things against your will. Things like working for BIG! Suddenly, he heard something. Beep!Beep! It was getting louder. Annoyed, Caz looked up from the ThoughtVision camera. ‘What is it, G5-382?’ she snapped. There was the clank of metal. Zac peered out from behind a stack of boxes. Another android security guard! ‘Heat sensors engaged,’ said the android in its dull robotic voice. ‘What?’ asked Caz, irritably. ‘Human heat detected in north-east quadrant of the room,’ droned the android.
